|---|---|
Pharmaceutical aluminum foil is used in blister lidding, cold-form Alu-Alu laminates, strip packs, tropical blister structures and other high-barrier pharmaceutical packaging. The correct material specification depends on whether the foil functions as a hard blister lid, a soft cold-forming aluminum layer, a sealing web or a component of a multilayer laminate.
The existing supply range includes AA8011, AA8021 and AA8079 with O, H14 and H18 conditions available according to application, thicknesses from 0.015 to 0.08 mm and customized widths typically from 50 to 1600 mm. Exact alloy, temper, gauge and surface requirements should be defined separately for each pharmaceutical packaging structure.
For conventional PTP blister lidding, hard-temper foil such as 8011-H18 is commonly selected together with a print primer or protective coating and a heat-seal lacquer. Cold-form Alu-Alu packaging instead requires a soft, highly formable aluminum layer, commonly 8021-O or suitable 8079-O, laminated with polymer layers such as OPA and PVC.
Pharmaceutical package qualification should consider the complete foil or laminate construction, forming web, lacquer, adhesive, printing system, pinhole limits, seal integrity, traceability and destination-market requirements rather than relying on aluminum alloy designation alone.

Discuss Your Pharmaceutical Packaging Structure
AA8011 in a hard temper such as H18 is commonly used as the aluminum substrate for conventional push-through blister lidding. The foil is typically combined with a protective or printable outer layer and a heat-seal lacquer on the sealing side.
A typical lidding structure can be expressed as protective coating or primer / printing ink where required / aluminum foil / heat-seal lacquer. Exact coating chemistry and coat weight depend on the forming web and packaging-line requirements.
Hard-temper foil provides the handling and push-through characteristics expected in conventional blister lidding. O-temper cold-forming foil should not be substituted automatically for H18 lidding material.
PTP aluminum commonly uses gauges around 20, 25 or 30 μm, but final thickness should follow the approved package design, blister-machine requirements, push-through performance and customer specification.
The heat-seal lacquer must match the forming web used by the blister package, such as PVC, PVDC-coated PVC, PP or another approved material. Seal temperature, pressure, dwell time and line speed should be validated using the actual package.
Where pharmaceutical information or branding is printed on the foil, specify the primer, ink system, printing process, curing requirements and protective overcoat where required.
AA8021 in O temper is widely selected as the aluminum layer in cold-form pharmaceutical laminates where high ductility is needed to form blister cavities at room temperature.
A common cold-form laminate is OPA / aluminum / PVC. The polyamide layer supports forming and mechanical performance, the aluminum provides the primary high-barrier layer, and the PVC surface provides compatibility with downstream blister packaging processes.
Cold-form laminates commonly use an aluminum layer around 45–60 μm. Total laminate thickness is substantially greater because the OPA, PVC, adhesive and other functional layers are added separately.
Cold-form performance depends on elongation, foil gauge, rolling direction, laminate construction, forming-tool geometry and cavity depth. The material should be validated using representative production laminate rather than bare foil properties alone.
Deep forming can create high localized strain. Adhesive bond strength and aluminum ductility should be controlled so the laminate forms without unacceptable cracking, layer separation or loss of barrier integrity.
AA8079 is used in selected pharmaceutical and high-barrier foil applications. Depending on temper and converter specification, it can be supplied for hard blister foil or as a soft, formable foil component in specialized laminates.
8079 should not be selected only because a package requires a higher barrier. An intact continuous aluminum layer is itself the principal barrier; alloy selection is more closely related to required mechanical properties, forming behavior, foil gauge, rolling quality and downstream converting.
Hard 8079 foil can be evaluated for blister lidding where its mechanical and converting characteristics meet the approved foil specification.
Soft 8079 foil can also be evaluated for high-elongation laminate applications where the converter requires specific tensile strength, elongation and surface characteristics.
| Selection Factor | PTP Blister Lidding | Cold-Form Alu-Alu |
|---|---|---|
| Function | Lidding web sealed over a formed blister cavity | Forming web itself is cold formed into the drug cavity |
| Typical Foil Condition | Hard temper | Soft O temper |
| Typical Alloy | 8011-H18; other approved hard foil alloys may also be used | 8021-O or suitable 8079-O |
| Typical Aluminum Gauge | Approximately 20–30 μm depending on design | Approximately 45–60 μm aluminum layer depending on laminate design |
| Typical Structure | Primer or OP / ink where required / Al / HSL | OPA / Al / PVC or another validated cold-form laminate |
| Main Mechanical Requirement | Stable lidding, printability and designed push-through behavior | High ductility and fracture-free cavity forming |
| Seal Requirement | HSL must match PVC, PVDC, PP or other approved forming web | Cold-form laminate normally works with a separate lidding web to complete the blister package |
Choose PTP or Cold-Form Pharmaceutical Foil
Tropical blister foil is a high-barrier aluminum-containing laminate used to enhance the protection of conventional thermoformed blister packaging. It is different from cold-form Alu-Alu even though both contain an aluminum barrier layer.
A typical tropical structure can use OPA / aluminum / heat-seal coating. It is formed around an existing thermoformed blister and heat sealed to the compatible blister web, adding another barrier layer without replacing the original formed cavity.
Tropical blister can be considered when a thermoformed blister needs additional moisture, light or gas protection but the manufacturer wants to retain the basic thermoforming process and blister cavity format.
The order specification should state the actual OPA, aluminum and heat-seal layer construction rather than using an ambiguous name. Total laminate thickness, forming behavior and sealing compatibility should be confirmed for the selected blister line.
Strip packaging encloses individual tablets, capsules or other dosage forms between sealing webs without using a preformed blister cavity. Aluminum-containing structures can provide high barrier protection when properly sealed.
Strip foil is normally softer than conventional PTP lidding because the material must conform around the dosage form during sealing. Gauge, lacquer, seal strength and tear characteristics should be matched to the strip-pack equipment and medicine geometry.
The seal must provide package integrity around the dosage form without excessive material distortion. Where seal strength is contract-critical, define the sealing conditions, specimen preparation, test method and acceptance range.
Opening performance should be evaluated with the complete strip construction. Foil thickness, laminate layers and sealant chemistry can all affect consumer opening force.
An intact continuous aluminum layer is opaque and provides an extremely effective barrier against light, moisture vapor and gases. This makes aluminum valuable for medicines that require protection from environmental exposure.
The finished pharmaceutical package is not determined by the aluminum layer alone. Pinholes, forming cracks, flex damage, adhesive failure, heat-seal defects, channel leaks and damage during converting can reduce package integrity.
Moisture-sensitive formulations require a complete packaging system with an appropriately low moisture transmission rate and reliable sealing. Final shelf-life performance should be established using the finished package and drug product.
The metal layer provides a strong gas barrier when intact, but actual package performance still depends on seals, edges, forming integrity and laminate construction.
Aluminum prevents direct light transmission through the intact metal layer and can therefore be used in packaging systems for light-sensitive pharmaceutical products.
A blanket “pinhole-free” claim should not replace a measurable quality specification. Pinhole frequency depends strongly on foil gauge, rolling quality and inspection sensitivity.
For barrier-critical pharmaceutical applications, specify the inspection method, minimum detectable pinhole size, allowable count, inspected area and sampling plan.
Very thin foil is more sensitive to pinhole formation, so pinhole criteria become increasingly important as gauge is reduced.
Cold-forming foil is thicker but must also survive high strain during cavity forming. Forming trials should confirm that unacceptable cracks or barrier defects are not created during production.
PTP blister foil normally requires a heat-seal lacquer on the side that contacts the forming web. Lacquer chemistry must be matched to the actual substrate and sealing conditions.
For conventional PVC blister webs, specify a heat-seal coating validated for the actual PVC formulation and the intended temperature, pressure and dwell time.
Where PVDC-coated PVC is used to increase barrier performance, verify that the lidding lacquer provides the required seal to the coated forming web.
PP and other polymers can require different heat-seal chemistry. Container or forming-film material should therefore be stated explicitly with the inquiry.
Where heat-seal coat weight is critical, specify the nominal value and tolerance together with the sealing substrate and required seal strength.
Pharmaceutical lidding often carries product identification, dosage information, batch coding and branding. The foil surface should therefore be compatible with the selected printing and coating process.
A printable primer can be applied where the converter requires stable ink adhesion. Primer chemistry should be matched to the chosen ink and curing system.
An outer protective lacquer can be used to protect printing where required. Resistance to heat, abrasion and downstream processing should be defined for the actual packaging line.
Where converting capability allows, foil can be specified as bare, primer-coated, lacquered or otherwise prepared for customer printing. The precise supply condition should be agreed before production.
PTP lidding and cold-form blister laminates are widely used for tablets and capsules. Selection depends on moisture sensitivity, light sensitivity, package size, dispensing method and production equipment.
Cold-form or enhanced-barrier structures can be considered for formulations requiring greater protection from water vapor than a conventional thermoformed blister provides.
Aluminum foil can be incorporated into flexible pharmaceutical laminates for powders and granules. The foil is only one layer of the package, so sealant film, adhesive, puncture resistance and compatibility with the contents should also be specified.
Soft foil structures can be used in strip packaging where paired webs seal around individual dosage forms without a separately formed blister cavity.
Confirm the ordered alloy and temper against the agreed material documentation. PTP hard foil and cold-form soft foil should not be interchanged without technical qualification.
Verify foil thickness using the agreed measurement method and tolerance. Gauge consistency affects winding, printing, sealing and forming performance.
Apply the agreed pinhole inspection method and acceptance criteria appropriate to the gauge and intended package.
Check for excessive rolling oil, particles, scratches, corrosion, stains and contamination that could interfere with coating, printing, adhesive bonding or pharmaceutical packaging cleanliness.
For foil that will be coated or laminated, surface condition should support the selected primer, lacquer or adhesive. Production trials are recommended for new chemistry or laminate constructions.
Check roll alignment, winding tension, telescoping, edge damage, core condition and other roll characteristics that can affect high-speed converting.
Before approving a new PTP or cold-form structure, test representative production material on the actual blister equipment using intended line speed, forming geometry, sealing conditions and forming film.
The finished pharmaceutical package should be qualified as a complete container-closure system. The aluminum foil is one component of that system and should be evaluated together with forming film, coating, adhesive, printing, seals and the pharmaceutical product.
The package should provide the level of moisture, oxygen, light and contamination protection required by the drug product throughout the intended shelf life and distribution environment.
Packaging components and coatings should be compatible with the pharmaceutical product and with each other under the intended manufacturing, storage and use conditions.
Blister and strip seals should be validated under representative processing and storage conditions. Heat-seal lacquer selection alone does not establish finished-package integrity.
Where pharmaceutical traceability is required, define the documentation linking supplied coils to production lots, material certificates and applicable inspection records.

Pharmaceutical aluminum foil is aluminum foil engineered for use as a lidding, forming, sealing or barrier component in blister packs, strip packs, cold-form laminates and other pharmaceutical packaging systems.
8011 in hard temper is widely used for conventional PTP blister lidding. 8021-O is widely used as a highly formable aluminum layer in cold-form Alu-Alu laminates. 8079 can be used in selected hard blister or soft laminate applications depending on temper and converter requirements.
Hard temper such as H18 is commonly used for conventional push-through blister lidding because the foil must retain stable lidding characteristics while allowing the dosage form to break through the designed lid.
O temper is commonly selected because high ductility is required when the aluminum-containing laminate is cold formed into blister cavities.
Common PTP aluminum gauges include approximately 20, 25 and 30 μm. Final gauge depends on push-through performance, converting equipment and the approved package specification.
The aluminum layer in cold-form laminates is commonly around 45–60 μm, but the finished OPA/Al/PVC laminate has a much greater total thickness.
PTP foil is normally a hard aluminum lidding web sealed over a formed blister. Alu-Alu is a soft, multilayer cold-forming web that is mechanically formed into the drug cavity itself.
A typical structure can include protective coating or printable primer, printing ink where required, aluminum foil and a heat-seal lacquer on the sealing side.
OPA / aluminum foil / PVC is a common cold-form structure. Exact polymer gauges, adhesive system and aluminum thickness depend on the approved package.
Tropical foil is an aluminum-based high-barrier laminate, commonly using an OPA/Al/HSL-type structure, that is added to enhance protection around a conventional thermoformed blister.
No. Cold-form Alu-Alu is the forming web used to create the cavity, while tropical foil is typically an additional high-barrier laminate used with a thermoformed blister structure.
Strip packaging seals dosage forms between paired webs without a preformed blister cavity. Aluminum-containing strip structures are selected according to seal strength, flexibility and required barrier performance.
Pinhole performance should be defined by an agreed inspection method and acceptance limit. Foil gauge strongly affects pinhole probability, so a measurable criterion is more appropriate than a blanket pinhole-free claim.
An intact continuous aluminum layer provides extremely high barrier performance and blocks light, but finished-package protection also depends on pinholes, forming integrity, laminate bonds and seals.
Yes, when the foil uses a heat-seal lacquer validated for the actual PVC forming web and production sealing conditions.
Yes, with an appropriate heat-seal system. The PVDC-coated forming web should be identified before lacquer selection and seal qualification.
Yes. Pharmaceutical lidding can be prepared with a suitable primer or coating for compatible printing processes. Ink, curing and protective-overcoat requirements should be approved before production.
Heat-seal lacquer can be specified where the supplied product and production capability include coating. The forming web, coat weight, sealing conditions and required seal strength should be defined.
Yes. Soft aluminum foil is widely used as a barrier layer in pharmaceutical laminates. Adhesive compatibility, surface cleanliness, wettability and forming requirements should be confirmed.
8021-O is more commonly associated with soft cold-forming applications. Do not substitute it directly for hard PTP lidding unless the complete blister structure has been technically qualified.
No. 8079 can be used in different pharmaceutical foil applications depending on temper and mechanical requirements. The packaging structure, not the alloy number alone, should determine selection.
No. Pharmaceutical packaging qualification includes the manufacturing and quality system, supplied material, coatings, traceability, package design and applicable regulatory requirements. Compliance scope should be confirmed through the relevant documentation.
Required documentation can be discussed for the exact supplied foil or laminate. Buyers should state the destination market and required regulatory, migration, quality or technical documents before production.
Typical qualification can include gauge, width, surface quality, pinholes, mechanical properties, printability, coating adhesion, seal strength, forming performance, laminate bond and package-integrity testing according to the application.
Custom width, core ID, roll OD and roll weight can be discussed within production capability. Provide the converting-machine requirements with the inquiry.
Foil rolls can be protected with moisture-resistant wrapping and suitable export wooden cases or pallets according to roll size, cleanliness and handling requirements.
The existing commercial reference is approximately 20–35 days. Actual lead time depends on alloy, temper, foil gauge, coating, printing, dimensions, quantity and production schedule.
Please provide packaging type, alloy and temper if known, foil thickness, width, core ID, roll dimensions, forming web or laminate structure, primer or heat-seal lacquer requirement, printing requirement, pinhole criteria, mechanical or forming requirements, sealing conditions, quantity, required documentation, packing requirement and destination.

Discuss Your Pharmaceutical Packaging Structure
AA8011 in soft or O temper can be selected for pharmaceutical strip packs and flexible laminate structures where flexibility, folding behavior and sealing compatibility are more important than the stiffness required by conventional hard PTP lidding.
Soft 8011 foil can conform around tablets or capsules in strip-pack applications where paired webs are sealed around the dosage form without a preformed blister cavity.
8011-O can be laminated with compatible polymer films, paper or sealing layers to create pharmaceutical sachets and flexible packaging. The complete laminate determines mechanical strength, sealing behavior and finished-package durability.
Surface preparation can be specified for primers, inks, lacquers or adhesives used by the converter. Exact coating chemistry should be matched to the downstream process.
AA8021 in O temper is commonly evaluated where a soft, ductile aluminum layer is required for pharmaceutical laminates and cold-form structures.
Cold-form Alu-Alu packaging normally uses a multilayer structure rather than bare aluminum foil alone. A common construction includes an OPA layer, a soft aluminum barrier layer and PVC, bonded with suitable adhesives.
Cold-form structures commonly use an aluminum layer in the upper part of the current 20–50 μm range or thicker, depending on the approved laminate design. Where 45–60 μm aluminum is required, final availability should be confirmed separately from the standard table.
Cold-form performance depends on aluminum elongation, laminate construction, adhesive bond, rolling direction, forming depth and cavity geometry. Representative laminate should be validated on the intended blister-forming equipment.
Deep cavity forming creates localized strain. Laminate adhesion and foil ductility should therefore be controlled to reduce cracking, delamination or other defects that can compromise package integrity.
AA1235 can be supplied for selected thin flexible-packaging and lamination applications where its foil characteristics match the converter's approved pharmaceutical package.
1235 should not be treated as a universal replacement for 8011 or 8021. Alloy selection should consider required mechanical properties, foil gauge, laminate construction, pinhole criteria and downstream converting conditions.
Where 1235 foil is laminated, surface cleanliness, residual oil, wettability and adhesive compatibility should be controlled for the actual adhesive and curing system.
Strip packaging differs from conventional blister packaging because tablets or capsules are sealed between flexible webs rather than placed in a separately thermoformed cavity.
Soft aluminum foil is suitable for evaluation in strip-pack structures because it can conform around the dosage form during sealing. Typical selection factors include foil thickness, softness, sealant system, printing surface and tear characteristics.
Foil gauges in the 20–50 μm range can be evaluated according to tablet or capsule geometry, required package stiffness and sealing structure. The final gauge should follow the validated strip-pack design.
Strip foil normally requires a compatible sealant coating, extrusion layer or laminate construction. The sealant should be selected according to the mating web, processing temperature and required package performance.
Where seal strength is critical, define sealing temperature, pressure, dwell time, specimen width, test speed and acceptance limits. Results from another laminate should not automatically be transferred to the new package.
Foil gauge, sealant and laminate layers influence tear and opening behavior. Consumer opening performance should therefore be evaluated using the completed strip structure.
Request Strip Packing Foil Specifications
Aluminum foil can be incorporated into flexible pharmaceutical laminates for powders, granules, supplements and other compatible products where protection from light, moisture or gases is required.
The aluminum layer is only one component of the finished sachet. Outer films, adhesives, sealing films, printing layers and package seams all influence mechanical performance and package integrity.
A pharmaceutical sachet may combine a printable outer film, adhesive, aluminum foil and an inner heat-seal film. The exact polymer types, gauges and adhesive system should be specified for the drug or healthcare product.
Very thin foil can be sensitive to repeated flexing. Package design and laminate layers should limit flex cracking where the finished pouch experiences bending during distribution or handling.
Finished sachet protection depends on the integrity of heat seals as well as the aluminum barrier layer. Seal strength and leak performance should be validated on the complete package.
| Selection Factor | Soft Pharmaceutical Foil | PTP Hard Blister Foil |
|---|---|---|
| Typical Temper | O / fully annealed soft condition | Hard temper such as H18 in conventional PTP structures |
| Main Function | Flexible sealing, strip packing, lamination or forming component | Rigid lidding web sealed over a formed blister |
| Mechanical Behavior | Higher flexibility and conformability | Higher hardness for stable lidding and controlled push-through behavior |
| Typical Uses | Strip packs, sachets, laminates, cold-form substrate | Tablet and capsule PTP blister lids |
| Coating | Sealant, adhesive treatment or laminate-compatible surface according to structure | Typically printable/protective outer coating plus HSL on the sealing side |
Cold-form pharmaceutical packaging should not be specified as bare 8021 aluminum foil alone. The finished forming material is normally a multilayer laminate designed to provide mechanical support, cold-formability and package compatibility.
Oriented polyamide provides mechanical support and helps distribute strain during cold forming.
The soft aluminum layer provides the principal metallic barrier and must withstand deformation without unacceptable cracking.
The inner polymer layer contributes to forming and compatibility with the finished blister package. Exact polymer and gauge depend on the approved laminate design.
An intact continuous aluminum layer provides very high resistance to light transmission and very low gas and moisture transmission through the metal itself.
Finished pharmaceutical-package protection depends on more than the base foil. Pinholes, flex cracks, cold-form damage, delamination, seal defects, seams and converting damage can all reduce package integrity.
Moisture-sensitive products should be evaluated using the complete finished package under the intended storage conditions. Foil alloy alone does not establish shelf life.
An intact aluminum layer provides strong oxygen protection, but seals and package defects must also be controlled to maintain the intended barrier.
Aluminum is opaque and blocks direct light transmission through the intact metal layer, making it useful in packages for light-sensitive pharmaceutical and healthcare products.
Pinhole performance should be specified using an agreed inspection method rather than a general “pinhole-free” statement. Foil gauge, rolling conditions and inspection sensitivity all affect observed pinhole results.
For barrier-critical packaging, specify the maximum allowable pinhole size, allowable count, inspected area and sampling plan.
Pinhole probability generally becomes more important as foil gauge decreases. A 20 μm foil should therefore not automatically be assigned the same pinhole acceptance criteria as a substantially thicker foil.
Barrier defects can also be introduced after rolling through folding, lamination, forming or excessive tension. Finished-package validation remains necessary even when incoming foil passes its pinhole specification.
The current product can be supplied with one-side or two-side treatment according to the downstream converting route.
Where gravure or flexographic printing is required, specify primer, ink chemistry, curing method, artwork requirements and any protective over-lacquer used by the converter.
Adhesive bonding requires controlled cleanliness and surface condition. Residual rolling oil or contamination can reduce laminate bond strength.
Two-side treatment can be specified when different surfaces will receive printing, protective lacquer, adhesive or sealant. Each side's functional requirement should be stated separately.
Pharmaceutical foil can carry product identification, dosage information, batch details and branding when the foil surface and coating system are suitable for the selected printing process.
For gravure printing, specify ink chemistry, primer, number of colors, curing conditions and required print resistance.
Flexographic printing can also be used on suitably prepared foil. Surface treatment and ink adhesion should be validated before bulk converting.
Where printing is exposed to abrasion, heat or downstream processing, a compatible protective coating can be specified according to the finished package design.
The primary use of this product range is pharmaceutical, nutraceutical and healthcare packaging where soft aluminum foil is required as a sealing, wrapping or laminate component.
Soft aluminum foil can be incorporated into compatible flexible laminates for pharmaceutical powders, granules, supplements and other suitable products.
Other foil packaging applications should be specified separately so alloy, temper, gauge and surface treatment can be matched to the actual product and converting process.
One-side treatment can be selected where only one surface requires primer, lacquer, adhesive or another converting treatment.
Both surfaces can be treated where different functions are required on the printing and sealing or laminating sides.
Transparent protective lacquer can be discussed where it is compatible with the intended pharmaceutical packaging structure and processing conditions.
Gold or other compatible colors can be discussed for approved packaging structures. Coating chemistry and documentation should be confirmed for the intended application.
Thickness within or adjacent to the listed 0.02–0.05 mm range and customized slit widths can be discussed according to alloy, application and production capability.
Core ID, roll OD, roll weight, winding direction and slit width can be specified according to the customer's converting equipment.

Confirm alloy and O/Soft temper against the agreed material documentation before lamination, printing or strip-pack converting.
Verify nominal thickness and tolerance using the agreed measurement method. Gauge consistency affects winding, lamination, sealing and mechanical behavior.
Inspect for excessive rolling oil, particles, scratches, stains and contamination that could interfere with primer, ink, adhesive or sealant adhesion.
For barrier-critical packaging, inspect pinholes according to the agreed test method and acceptance criteria.
Where treated foil is ordered, verify that the correct side or both sides provide suitable surface condition for the intended coating, printing or adhesive system.
Check width, edge quality, burr and roll alignment against the requirements of the receiving equipment.
Verify winding tension, telescoping, loose layers, core condition and edge alignment before high-speed converting.
For a new laminate, coating, adhesive, strip pack or pharmaceutical package, test representative production foil on the actual converting equipment before bulk approval.
Pharmaceutical packaging performance should be evaluated as a complete packaging system. The aluminum foil is one component and should be considered together with coatings, adhesives, sealing films, forming layers, printing and the packaged product.
The finished package should provide the level of moisture, gas, light and contamination protection required for the pharmaceutical or healthcare product throughout its intended storage and distribution conditions.
Foil, coatings, adhesives, sealants and other package layers should be compatible with each other and with the packaged product under the intended conditions of use.
Seals, laminate bonds and package edges should be validated because a high-barrier aluminum layer cannot compensate for an incomplete seal or damaged laminate.
Where required, purchase specifications should define batch identification, material certificates, test reports and other documentation needed to trace supplied foil to its production lot.
State whether the foil is intended for strip packaging, sachets, flexible pharmaceutical laminates, cold-form lamination or another medical-packaging structure.
Specify 8011, 8021 or 1235 where already approved. If the alloy has not been fixed, provide mechanical, forming and converting requirements.
The current product range is O / Soft. Do not substitute it for hard PTP blister foil without separate technical qualification.
Provide nominal thickness and tolerance. The existing range is 0.02–0.05 mm.
Provide jumbo-roll or finished slit width together with the required tolerance.
State whether one-side treatment, two-side treatment, primer, lacquer or adhesive-ready foil is required.
For strip packs and sachets, provide the mating web, sealant polymer, adhesive or complete laminate construction where known.
State gravure, flexographic or other printing process, together with primer, ink, curing and protective-coating requirements.
Specify the required pinhole inspection method, detection size, allowable count and sampling plan when barrier performance is critical.
Provide core ID, maximum OD, roll weight, winding direction and splice requirements according to the converting machine.
State required material certificates, batch traceability, coating or migration documents, inspection reports and destination-market requirements before production.

Soft pharmaceutical aluminum foil is fully annealed or soft foil used in strip packs, flexible laminates, sachets and selected forming applications where flexibility and conformability are required.
The current product specification lists 8011, 8021 and 1235.
The current product range is O / Soft temper.
The existing product range is 0.02–0.05 mm, equivalent to 20–50 μm.
Yes. Soft foil in this gauge range can be evaluated for compatible strip-pack structures where alloy, foil gauge, sealant, printing and opening requirements meet the approved package design.
No. Conventional PTP blister lidding normally uses hard-temper foil such as 8011-H18, while this page primarily covers soft O-temper pharmaceutical foil.
Not without technical qualification. The two tempers have different mechanical behavior and are intended for different packaging functions.
Yes, 8021-O is commonly used as the aluminum layer in suitable cold-form laminates. The complete OPA/aluminum/PVC or other approved laminate structure must be specified separately.
Typical cold-form aluminum layers are generally thicker than 20 μm. The required gauge should follow the validated laminate specification and forming depth rather than the minimum range shown on this page.
1235 can be evaluated for selected flexible pharmaceutical laminates where its foil properties and surface condition meet the approved package specification.
Yes. Suitable surface treatment can support gravure, flexographic or other compatible printing systems. Primer and ink requirements should be specified before production.
Yes, where compatible with the production route. The required treatment or coating on each side should be identified separately.
Compatible pharmaceutical-packaging lacquers can be discussed according to the required sealing, printing, protection or decorative function.
Yes. Soft aluminum foil is commonly incorporated into multilayer pharmaceutical packaging. Adhesive chemistry, curing conditions and laminate bond should be validated with the actual materials.
An intact continuous aluminum layer provides very strong moisture-barrier performance, but the finished package also depends on pinholes, flex damage, seals and laminate integrity.
Yes. An intact aluminum layer is opaque and blocks direct light transmission through the metal.
Pinhole performance should be controlled using an agreed inspection method and acceptance criteria. Thin foil should not be described by an unconditional pinhole-free claim.
As foil becomes thinner, rolling defects and very small discontinuities become more important to barrier performance. Acceptance criteria should therefore be appropriate to the selected gauge.
Yes, where the foil is incorporated into an approved flexible laminate with suitable outer, adhesive and heat-seal layers.
Aluminum-containing sachet laminates can be used for compatible powders and granules. The complete laminate and sealant should be evaluated for the actual contents and storage conditions.
It can be evaluated for nutraceutical and supplement packaging where the material structure, regulatory requirements and packaged product are compatible.
No. Pharmaceutical packaging suitability depends on the complete material structure, manufacturing controls, coatings, adhesives, traceability, package design and applicable regulatory requirements.
Required documentation can be discussed for the exact supplied foil, treatment or laminate. Buyers should identify the destination market and required document scope before production.
Typical checks can include alloy, temper, thickness, width, surface cleanliness, pinholes, mechanical properties, wettability, coating or adhesive compatibility, printability, seal strength, roll quality and finished-package integrity.
Custom widths, core ID, roll OD and roll weight can be discussed according to production capability and the receiving converting equipment.
The existing product information uses moisture-resistant export packing with reinforced wooden cases and eye-to-wall or eye-to-sky roll orientation where suitable.
The existing commercial reference is approximately 15–20 days. Actual delivery time depends on alloy, gauge, width, surface treatment, quantity and production schedule.
Please provide packaging application, alloy and temper if known, foil thickness, width, core ID, roll dimensions, one-side or two-side treatment, laminate or sealing structure, printing process, pinhole requirement, forming or sealing conditions, required technical documentation, quantity, packing requirement and destination.
