About aluminum plastic film material?

The pouch battery is packaged with aluminum-plastic film, which is a composite material and consists of three layers: nylon layer, aluminum foil layer, and heat-sealing layer.

Classification of aluminum-plastic film:

aluminum foil composite film, paper-aluminum composite film, aluminum-containing composite film, non-printing composite film, pharmaceutical aluminum-plastic composite film, etc.

Aluminum foil has a highly dense metal crystal structure, high barrier properties, high strength, good elongation and compressibility, and is mainly used as a group spacer.

Aluminum-plastic film: extremely high barrier properties; good cold stamping formability; puncture resistance; resistance to electrolyte stability; electrical properties (including insulation).
