Description
8021 Aluminum Foil is a key aluminum foil product for food packaging and battery soft-pack applications. 8021 aluminum foil offers excellent moisture resistance, light blocking, and high barrier properties. It is non-toxic, odorless, safe, and hygienic. After lamination, printing, and gluing, aluminum foil is widely used as a packaging material.
8021 aluminum foil is also commonly used as pharmaceutical and packaging foil.
8021 aluminum foil belongs to the 8-series aluminum alloy, with iron (Fe 1.2-1.7%) as the primary alloying element. Through optimized alloying ratios and processing techniques, comprehensive performance enhancements are achieved.
Specific advantages of 8021 aluminum foil:
1. High elongation and puncture resistance: A special process significantly increases the elongation of 8021 aluminum foil, making it suitable for deep drawing, such as the complex stamping of aluminum-plastic film for battery soft-pack applications, ensuring the material is resistant to cracking or delamination.
2. Excellent Barrier Properties: 8021 Aluminum Foil offers outstanding barrier properties against moisture, light, and oxygen, effectively extending product shelf life in food packaging and meeting high sealing requirements in pharmaceutical packaging.
3. Stable Thermal Performance: 8021 Aluminum Foil remains stable within a temperature range of 130°C to 200°C, making it suitable for high-temperature sterilization and heat-sealing processes. For example, PTP pharmaceutical aluminum foil exhibits excellent heat-seal strength and sealing properties.
4. Stringent Surface Quality: Through precision rolling and slitting processes, 8021 Aluminum Foil achieves a clean, oil-free surface with a wetting tension exceeding 32 dynes, meeting the printing and lamination requirements of high-end packaging.
Applications of 8021 Aluminum Foil:
1. Food and Pharmaceutical Packaging
Food Industry: Suitable for packaging such as vacuum-cured prepared foods, high-end ice cream, and barbecue foil. Its moisture-proof and light-blocking properties ensure food quality, while its surface smoothness supports high-quality printing. Pharmaceuticals: In cold-stamped aluminum foil (PTP) and blister packaging, high cupping and heat-seal strength ensure drug sealing and compliance with pharmaceutical hygiene standards.
2. New Energy Batteries
In power battery soft-pack aluminum-plastic film, 8021 aluminum foil, with its high elongation and corrosion resistance, protects battery cells from external environmental influences while also contributing to battery lightweighting and increased energy density. With the rapid development of the new energy industry, demand for this application continues to grow.
3. Industrial and Electronics
As a cable shielding material, it offers outstanding electrical conductivity and electromagnetic interference resistance. In electronic device heat dissipation components, it offers significant advantages in thermal efficiency and lightweighting, making it suitable for applications such as 5G base stations and consumer electronics.
