Aluminum plastic film is a multilayer film composed of an outer nylon layer, an adhesive, an intermediate aluminum foil layer, an adhesive, and an inner heat-seal layer. It is a key material for packaging soft-cell lithium battery cells. It has the advantages of light weight, high safety factor, and good recyclability. It has an important impact on many battery performances. At present, the market is mainly monopolized by Japanese and Korean companies.
Market size forecast
In 2018, the global demand for aluminum-plastic film was about 348 million square meters, of which 3C consumer battery demand accounted for 88.6%. It is estimated that by 2020, global demand will exceed 510 million square meters. With the continuous increase in the penetration rate of new energy vehicle power battery soft packs, the demand for aluminum and plastic films for power batteries will exceed 107 million square meters, accounting for 20.8%.
