Introduction of 8079 O Aluminum foil for flexible package
8079-O aluminum foil is specifically designed for the **flexible packaging** sector. As a flagship product of the 8000 series aluminum-iron-silicon alloys, it offers comprehensive improvements over traditional pure aluminum foil in terms of pinhole control, mechanical properties, and processability, making it the core substrate for high-end flexible packaging markets such as food, pharmaceuticals, and personal care products. Key Performance Advantages. Compared to traditional pure aluminum foils such as 1235 and 1100, the 8079 alloy achieves a significant leap in performance across multiple key dimensions by optimizing the ratio of iron (Fe) and silicon (Si).
Main Features:
- Ultra-low pinhole rate: The number of pinholes is significantly lower than in traditional aluminum foil. Its dense metallic structure provides excellent oxygen barrier, moisture barrier, and light-blocking properties—which are fundamental to ensuring the long-term shelf life of packaged contents (especially pharmaceuticals and food).
- Superior mechanical properties: In the O-state (annealed soft state), it exhibits excellent flexibility and elongation, making it resistant to breakage during deep drawing, stretching, lamination, and other processing operations on high-speed packaging lines, thereby significantly improving yield rates.
- Outstanding surface quality: The sheet surface is flat with a high degree of smoothness, free of defects such as oil stains or oxidation, making it perfectly suited for high-precision printing and coating processes to produce an exquisite packaging appearance.
- International Safety Compliance: The material complies with international food contact standards such as those set by the FDA and the EU, making it a safe choice for export to high-end markets.
Applications
This product serves as the core barrier layer in numerous high-end flexible packaging solutions. Major applications include:
- Pharmaceutical Packaging: Sealing bottom foil for blister packaging (PTP), providing moisture and light protection for tablets and capsules.
- Food Packaging: Laminated film packaging for premium foods such as chocolate, candy, dairy products, snacks, and condiments, used to preserve freshness and aroma.
- New Energy: A key barrier layer material for aluminum-plastic films in pouch-type lithium-ion batteries.
- Personal Care and Industrial: High-end sealed packaging for skincare products and cosmetics, as well as moisture-proof liners for precision electronic components.
