8021 aluminum foil belongs to 8000 series aluminum alloy. At present, the aluminum foil alloy for soft pack batteries is mainly 8021 aluminum alloy foil. JC Metal 8021 aluminum foil for soft pack batteries has excellent punching and puncture resistance. After testing, the elongation rate can reach 13%-18%, and the cup height can reach 7.3mm. 8021 aluminum foil can be composited, printed and bonded to become packaging materials. For example, pharmaceutical packaging and food packaging.

Chemical Composition



1. Good extensibility. Good deep drawing performance, good electrolyte corrosion resistance, high heat seal strength. Often used in deep-drawing packaging materials.
2. Strong mechanical properties, high explosion resistance, strong puncture resistance and tear resistance.
3. The surface is smooth and clean, with uniform color, no spots and no oil stains. The most important thing is no pinholes. So, it has excellent moisture-proof, light-shielding and extremely high barrier capabilities.
4. High and low-temperature resistance. Will not cause oil leakage due to temperature changes.
