The aluminum-plastic film protects the internal electrode and insulates the external environment. In soft pack lithium battery, aluminum-plastic film accounts for 10-20% of the total material cost, second only to cathode material and diaphragm, with high technical barrier and low localization rate.

Black film (aluminum-plastic film), as a subdivision category, is mainly made of flow polypropylene film and black masterbatch (carbon black, additives, etc.) mixed flow made, used in apple battery and high-end consumer electronics battery. The main advantages of black film are: 1) make the text printed on the aluminum plastic film better; 2) Carbon black improves the smoothness of the outer surface of the aluminum-plastic film and enhances the punching performance; 3) Carbon black can improve the chemical resistance and prolong the life of batteries. Steel plastic film is the Flexible aluminium foil 1235 7 Micron layer of aluminum plastic film is replaced by stainless steel foil and alloy foil. Compared with aluminum-plastic film, the performance of steel - plastic film is improved in puncture resistance, mechanical strength, wear resistance and corrosion resistance.
Aluminum-plastic film specific material performance requirements aluminum-plastic film from the inside to the outside respectively for heat sealing layer, aluminum foilFlexible aluminium foil 1235 7 Micronerally composed of flow-casting polypropylene film.
Alufoil layer is mainly composed of metal aluminum or aluminum ferroalloy, which mainly prevents water vapor from penetrating into the inner part of the cell by forming an oxide film with oxygen. Alu foil layer in the aluminum film raw material cost accounted for 59%, 35% in the production cost. Nylon layer has good impact resistance and high puncture resistance, mainly to protect the aluminum foil layer from being scratched.
