Aluminum-plastic composite film (aluminum-plastic film for short) is a special packaging material for lithium ion battery, which is often used in soft package battery and blade battery. After assembly, a single cell is sealed inside an aluminum-plastic membrane to form a battery. 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.
