Aluminum plastic film is generally composed of nylon layer, adhesive layer, aluminum foil, protective layer, adhesive layer, and CPP layer. After the single cell battery is assembled, it is sealed with an aluminum-plastic film to form a battery, and the aluminum-plastic film plays a role in protecting the contents.
Due to the presence of electrolyte inside the battery, the aluminum-plastic film of the pouchage material is required to be able to resist the swelling, dissolution and absorption of organic solvents (electrolyte), while ensuring strict barrier of oxygen and moisture.
From the perspective of the aluminum-plastic film industry chain, upstream materials include calendered aluminum foil, nylon, adhesives, polypropylene and other materials, and the midstream includes processing equipment, testing equipment, etc., and related industries will usher in development opportunities.
At present, the aluminum-plastic film market is mostly occupied by many companies, especially in the power and high-end consumer markets. With the rapid growth of the global electric vehicle market and the relatively conservative expansion of Japanese-style companies, it may bring alternatives to China aluminum-plastic film companies. Chance.
DM aluminum-plastic film covers high-performance, high-quality lithium battery aluminum-plastic composite film for digital, energy storage, and power applications. Main products： The products are mainly divided into aluminum-plastic composite film silver film and aluminum-plastic composite film black film.
According to the statistics of China Chemical and Physical Power Industry Association, Selen Science and Technology has reached 87% of the China power-type aluminum-plastic film market share in 2020, and is the largest China power-type aluminum-plastic film supplier.
