Which aluminum alloy is used for aluminum-plastic composite film?

Aluminum-plastic composite film, also known as "aluminum-plastic film", is the outer packaging material for soft-packed lithium-ion batteries. In order to ensure the long-term stable operation of the battery, the aluminum-plastic film needs to have extremely high barrier properties, good cold stamping formability, Puncture resistance, electrolyte stability and insulation. Therefore, aluminum-plastic film is a high-strength, high-barrier multilayer composite structure composed of various plastics, aluminum foil and adhesives. In order to meet the performance requirements of the pouch battery.

The soft-pack battery is made of aluminum foil, plastic film, and special glue, which is commonly called aluminum-plastic film, and the surface of the aluminum foil is coated with lithium iron phosphate and lithium manganate ternary materials to make the inner core of the soft-pack battery. The inner core is placed in the finished aluminum-plastic film to make batteries for electronic products that are commonly used by everyone now, and to replace more lead-acid batteries is what we call lithium batteries.

Commonly used aluminum alloys for aluminum-plastic composite films include 1235 aluminum foil, 1060 aluminum foil, 1070 pure aluminum foil, 8021 aluminum foil, etc., with a thickness of 0.012-0.04mm. (MC only produces aluminum foil substrates for aluminum-plastic films, not finished aluminum-plastic films.)

The aluminum foil produced by MC Aluminum has multiple advantages such as clean oil removal, less holes, good product shape, and no deformation when cutting. It can be customized according to customer needs, and can undertake orders of 1-200 tons of aluminum foil. The products are exported to many overseas countries, and after-sales service is guaranteed.
