Cold Forming Aluminum Foil
Cold Forming Aluminum Foil
Pharmaceutical Grade Primary Packaging Material (Audit-Ready Supply)
Product Overview
Cold Forming Aluminum Foil (Alu-Alu foil) is a pharmaceutical-grade primary packaging material designed for highly sensitive solid dosage forms requiring maximum environmental protection throughout shelf life.
The material is formed at ambient temperature using a deep-drawing process, creating a rigid aluminum cavity structure that provides complete isolation from moisture, oxygen, and light exposure.
It is widely used in regulated pharmaceutical applications, including:
- Hygroscopic tablets and capsules
- Oncology and cytotoxic medications
- Antibiotics and anti-infective drugs
- Cardiovascular and chronic disease treatments
- Clinical trial and reference products
Barrier Performance
Cold forming aluminum foil provides one of the highest barrier performances available in pharmaceutical blister packaging materials.
Key Performance Indicators
1. Water Vapor Transmission Rate (WVTR): ≤ 0.01 g/m²/day
- Test Method: ASTM F1249
- Standard Conditions: 38°C / 90% RH
2. Oxygen Transmission Rate (OTR): ≈ 0 cc/m²/day
- Test Method: ASTM D3985
Functional Principle
The barrier performance is achieved through a continuous aluminum layer that acts as a non-porous metallic shield, ensuring:
- Zero moisture permeation
- Zero oxygen diffusion
- Zero light transmission

FAQ
Q: What is cold forming aluminum foil used for?
A: It is used in pharmaceutical blister packaging applications requiring maximum protection against moisture, oxygen, and light for highly sensitive drug products.
Q: How does it differ from PVC or PVDC blister materials?
A: Cold forming aluminum foil provides a non-porous aluminum barrier system, while PVC and PVDC rely on polymer diffusion resistance and cannot achieve absolute barrier performance.
Q: Is the material suitable for high-speed blister packaging lines?
A: Yes. It is designed for stable performance on major pharmaceutical blister packaging equipment, including Uhlmann, IMA, and Mediseal, under validated operating conditions.
Q: Can third-party testing be arranged?
A: Yes. Testing can be conducted through internationally recognized laboratories such as SGS, Intertek, or TÜV based on customer qualification requirements.
Q: Do you support supplier audits?
A: Yes. We provide documentation support and manufacturing system information required for supplier evaluation. On-site or remote audits can be arranged during qualification stages.
Q: What are your MOQ and lead time?
A: MOQ and lead time depend on specification requirements, order volume, and customization needs. We support both trial orders and long-term supply agreements.
