Hemaokang Steel (Shandong) Co., Ltd. is proud to present our Cold Formed Alu Alu Foil (0.045mm thickness), specifically engineered for the demanding requirements of sensitive drug blister packaging. As a manufacturer with ISO9001 certification and an annual export value exceeding US$50 million, we combine precision engineering with rigorous quality control to deliver foil that provides an exceptional barrier against moisture, oxygen, and light. This product is designed to maintain the integrity of hygroscopic and light-sensitive pharmaceuticals, ensuring patient safety and extended shelf life.
Our cold-formed aluminum foil is manufactured using advanced cold forming technology, which imparts superior mechanical properties compared to hot-formed alternatives. The 0.045mm thickness offers the perfect balance between formability and barrier protection, making it ideal for push-through blisters, clamshell packs, and unit-dose packages. Below, we detail the key features, technical specifications, and benefits that set our foil apart in the global pharmaceutical packaging market.
Key Features & Technical Specifications
- High Barrier Performance: The cold-formed aluminum structure provides an extremely low water vapor transmission rate (WVTR) and oxygen transmission rate (OTR), ensuring long-term protection for sensitive drugs.
- Precision Thickness Control: Our 0.045mm foil is manufactured with a thickness tolerance of ±5%, ensuring consistent forming and sealing performance across batches.
- Excellent Formability: Cold forming allows the foil to be drawn into deep cavities without cracking or pinholing, accommodating complex blister shapes.
- Surface Cleanliness: The foil is free from oil residues, dust, and other contaminants, meeting pharmaceutical cleanroom standards.
- Compatibility: Works seamlessly with standard blister packaging machines (e.g., Uhlmann, IMA, Marchesini) and can be combined with heat seal lidding foils or PVC/PVDC laminates.
- Customizable Dimensions: Available in various widths (200–600 mm) and roll lengths (up to 3000 m per roll) to suit your production needs.
- ISO9001 Certified Quality: Our entire production process is ISO9001 certified, ensuring traceability and consistent quality.

Why Choose Our Cold Formed Alu Alu Foil?
- Superior Barrier Protection: The cold-formed structure creates a dense, pinhole-free barrier that is essential for moisture-sensitive drugs like antibiotics, insulin, and vaccines.
- Cost-Effective Production: Our cold forming process reduces material waste compared to hot forming, and the 0.045mm thickness optimizes material usage while maintaining strength.
- Global Compliance: Our foil meets international pharmacopoeia standards (e.g., USP, EP) for primary packaging materials, making it suitable for export worldwide.
- Enhanced Machine Compatibility: The foil’s consistent flatness and surface finish ensure smooth feeding and forming on high-speed blister machines, reducing downtime.
- Customization Options: We offer tailored solutions including printed registration marks, glue dots, or slider coatings to improve process efficiency.

Frequently Asked Questions (FAQ)
1. What is the difference between cold formed and hot formed alu alu foil?
Cold formed foil is produced by rolling aluminum at room temperature, resulting in a harder, more dimensionally stable material with higher barrier properties. Hot formed foil is processed at elevated temperatures, which can lead to softer material and potential surface defects. Cold formed foil is preferred for sensitive drugs requiring maximum protection.
2. Is this foil suitable for all types of sensitive drugs?
Yes, our 0.045mm cold formed alu alu foil is specifically designed for hygroscopic, oxygen-sensitive, and light-sensitive drugs. It is commonly used for antibiotics, cardiovascular drugs, hormones, and biologics. However, we recommend conducting compatibility tests with your specific formulation.
3. What is the typical thickness tolerance?
Our standard thickness tolerance is ±5% of 0.045mm. For tighter tolerances (e.g., ±3%), we can produce on request, subject to process capability.
4. Can you supply custom widths and roll lengths?
Absolutely. We offer widths from 200 mm to 600 mm, and roll lengths up to 3000 meters. Custom slitting and packaging are available upon request.
5. How do you ensure the foil is clean and free from contaminants?
Our production is carried out in a controlled environment. The foil is degreased, polished, and packed in sealed polyethylene bags. We also perform surface cleanliness tests (e.g., oil residue test) for each batch.
6. Do you have any certifications for pharmaceutical packaging?
We are ISO9001 certified. Our foil complies with the general requirements of pharmacopoeias (USP, EP) for aluminum packaging materials. Specific certificates (e.g., DMF) can be provided upon request.
7. What is the typical lead time?
For standard specifications, lead time is 15–20 working days. Custom orders may require 25–30 days, depending on quantity and complexity.
8. Can I get a sample before placing a bulk order?
Yes, we provide free samples (freight collect) for qualification. Please contact our sales team with your requirements, and we will arrange a sample roll.
