Product Description

Medical-Standard Lacquered Aluminum Foil for Moisture-Sensitive Capsules

Product Overview

The Molecular Moisture Lock

When packaging highly hydroscopic formulations, even microscopic traces of water vapor transfer can cause chemical hydrolysis or physical deformation of the capsule shell. Our medical foil acts as a total physical block. With a Water Vapor Transmission Rate (WVTR) effectively approaching absolute zero, it completely isolates the blister cavity from external atmospheric shifts, acting as a structural shield in hot, high-humidity climates.

Micro-Layer Coating Dynamics

To ensure clean processing and tight containment, our medical foil features a multi-tiered surface architecture. The interior facing is applied with an ultra-uniform layer of heat-seal lacquer that bonds at a molecular level to PVC, PVDC, or Alu-Alu forming films. This ensures that every individual capsule cavity is hermetically isolated from its neighbors, preserving the stability of the remaining doses when one is removed.

Product Advantages

Engineered for Critical Therapy Protection

Absolute Moisture Vapor Defense

Eliminates the risk of capsule brittleness or hydrolysis, ensuring stable dissolution profiles across the product lifecycle.

Clean Push-Through Fracture

The specialized H18 hard temper provides maximum stiffness, fracturing instantly under finger pressure without elastic elongation, protecting delicate capsule walls from deformation during extraction.

Certified SFDA & Global Compliance

Fully backed by comprehensive chemical and toxicological dossiers matching SFDA (Saudi Arabia), SASO, FDA, and GMP requirements for direct medical contact.

Zero-Defect Surface Cleanliness

Manufactured with inline laser inspection arrays to guarantee an entirely pinhole-free matrix across every production run.

Engineering Zero-Permeability Barrier Systems for Unstable Pharmaceutical Formulations

Gelatin and hydroscopic vegetable-based (HPMC) capsules are highly sensitive to environmental factors. Relative humidity variations can lead to capsule softening, stickiness, or cross-linking delays, rendering the medication ineffective. Structural integrity requires an unyielding, gas-tight environmental seal. Our Medical-Standard Lacquered Aluminum Foil is chemically and metallurgically engineered to solve this vulnerability. Utilizing ultra-pure, hard-temper 8011-H18 aluminum alloy, this premium lidding material delivers an absolute barrier against moisture vapor, safeguarding the chemical stability and shelf-life of high-stakes therapeutics.

Manufacturing Process

As a professional manufacturer since 2002, our manufacturing protocols fulfill the rigorous safety criteria demanded by global healthcare networks:

Class 100,000 Clean-Room Processing

To guarantee microbiological purity, all lacquered coatings, slitting, and packaging steps occur inside isolated, positive-pressure clean rooms.

High-Temperature Thermal Curing

Our lacquers undergo an optimized thermal baking cycle, ensuring zero residual solvents or chemical off-gassing that could react with sensitive capsule active ingredients.

Industrial Applications

Validated for High-Sensitivity Formulations

Our medical-grade foil is the designated protection medium for sensitive, high-value oral solids:

Gelatin & HPMC Hard Capsules

Preventing moisture-driven capsule melting, distortion, or structural sticking.

Softgel Nutritional Supplements

Protecting sensitive liquid-filled core oils from oxidation and humidity breach.

Dry Powder Inhaler (DPI) Capsules

Ensuring absolute dryness for ultra-fine micro-powders where clumping compromises dosage delivery.

Highly Hydroscopic Generic Therapeutics

Safeguarding unstable formulations without the need for cost-intensive desiccant strips.

FAQ

Why is 8011-H18 alloy critical specifically for capsule blister packaging?

Soft-temper foils tend to bend and stretch under pressure. If a consumer attempts to push a fragile capsule through a soft foil, the foil will deform, squeezing the capsule shell and potentially cracking or breaking it. The hard H18 temper snaps instantly, releasing the capsule cleanly.

How does this foil manage stability challenges in hot, humid target regions?

Can the exterior side be printed with customized multi-color medical tracking codes?

How do you protect the foil surface from micro-pinholes during the rolling process?
