8011 H22 Aluminum Foil for Food Containers & Packaging

8011 H22 Aluminum Foil for Food Containers and Packaging

8011 H22 aluminum foil is a partially annealed aluminum-iron-silicon alloy foil developed for packaging and converting applications that require more rigidity than fully annealed foil while retaining useful formability. It is particularly suitable for semi-rigid food containers, takeaway trays, bakery containers, formed packaging components and selected laminated packaging structures.

The product is available from 0.012 mm to 0.2 mm thickness with customized widths. Standard surface configurations can include bright and matte finishes, while transparent lacquer, colored coatings, printing, lamination and single- or double-side coating can be supplied according to the finished packaging structure.

H22 temper is strain hardened and then partially annealed to approximately quarter-hard strength. Compared with O temper, it provides greater rigidity for handling and forming, while remaining more formable than harder tempers such as H18. Final temper selection should be matched to the container geometry, foil thickness, stamping process and downstream converting requirements.

Why Choose 8011 H22 Aluminum Foil?

Balanced Strength and Formability

H22 temper offers greater stiffness than fully annealed O-temper foil while maintaining useful ductility for suitable stamping, drawing, flanging and container-forming processes. This balance makes it practical for semi-rigid packaging where the finished part must retain its shape after forming.

Barrier Against Moisture, Oxygen and Light

Continuous aluminum foil provides a strong barrier against water vapor, oxygen, light and external contamination. For very thin gauges, finished barrier performance also depends on pinhole level, converting damage, coating integrity and laminate construction.

Clean Surface for Printing, Coating and Lamination

Surface cleanliness and controlled winding are important for downstream printing, lacquering, adhesive lamination and heat-seal coating. Surface treatment and wettability requirements can be specified according to the converter's ink, lacquer and adhesive system.

Corrosion Resistance and Product Protection

8011 aluminum foil provides good resistance to normal atmospheric oxidation and is widely used as a barrier layer in food, household and industrial packaging. Suitability for direct product contact should be confirmed according to the coating system, packaged product and applicable market requirements.

Technical Specifications

Specification note: Mechanical properties vary with thickness, temper and testing direction. For forming applications, the required tensile strength, elongation, thickness tolerance, pinhole level and surface condition should be confirmed before volume production.

8011 H22 vs. O, H18 and H24 Tempers

8011 H22 for Formed and Semi-Rigid Packaging

H22 is approximately quarter hard after strain hardening followed by partial annealing. It offers a useful balance between rigidity and ductility and is commonly evaluated for food containers, trays and other formed packaging where shape retention is important.

8011-O for Soft Flexible Packaging

O temper is fully annealed and provides substantially greater softness and flexibility. It is commonly selected for household foil and flexible laminate applications where the foil must conform easily and high rigidity is not required.

8011-H18 for Hard Lidding and Pharmaceutical Foil

H18 is full hard and provides greater tensile strength with lower ductility. It is commonly selected for hard pharmaceutical PTP blister lidding and other flat lidding structures where rigidity, web stability and puncture behavior are more important than deep forming.

8011-H24 for Higher-Rigidity Container Foil

H24 is partially annealed to approximately half-hard condition and provides greater strength than H22. It can be evaluated for formed container applications where increased rigidity is required and the selected forming geometry remains compatible with the lower ductility.

Packaging Applications

Food Containers and Semi-Rigid Trays

8011 H22 is well suited to evaluation for takeaway food containers, bakery trays, ready-meal trays, airline catering containers and similar formed packaging. The required gauge should be selected according to container depth, flange geometry, embossing and stacking requirements.

Dairy and Food Lidding Structures

8011 foil can be used as a base material for coated and laminated lidding structures for yogurt, cream, dairy products and other food packaging. The required temper, primer, printing surface and heat-seal lacquer should be selected according to the container substrate and sealing process.

Confectionery and Flexible Packaging Laminates

8011 aluminum foil can function as the metallic barrier layer in suitable laminated structures for chocolate, confectionery, dry foods, sachets and industrial flexible packaging. Softer tempers may be preferable when very high flexibility is required.

Pharmaceutical Packaging

8011 alloy is widely used in pharmaceutical packaging, but the correct temper depends on the package design. Hard PTP blister lidding commonly uses H18 rather than H22. Any pharmaceutical application should specify foil temper, gauge, pinhole limits, surface cleanliness, lacquer system and applicable regulatory documentation separately.

Household and Industrial Packaging

The alloy can also be converted into household, technical and industrial packaging structures where foil barrier performance, light weight and compatibility with coatings or laminates are required.

Surface Quality and Converting Performance

Printing

Clean and uniform foil surfaces can be prepared for suitable printing processes. Buyers should specify printing method, primer requirement, corona or surface-treatment requirement and target surface tension where ink adhesion is critical.

Lamination

Foil can be laminated with paper, polymer films and other substrates to create barrier packaging structures. Adhesive system, foil surface condition and laminate curing requirements should be matched to the converter's process.

Heat-Seal Coating

Heat-seal lacquer can be applied for compatible lidding applications. Seal temperature, dwell time, pressure, substrate type and required seal strength should be specified because these parameters determine finished sealing performance.

Transparent and Colored Lacquer Options

Transparent lacquer, gold-tone finishes and other colored coating options can be discussed for packaging applications requiring branded appearance or additional surface protection. Single- or double-side coating is available subject to the confirmed coating construction.
