At present, the packaging methods of lithium batteries mainly include hard-shell batteries and soft-pack batteries. The soft-pack battery has the characteristics of light weight, thin thickness, flexible shape design, and has obvious advantages in safety, specific capacity, internal resistance, etc., and is gradually replacing the traditional hard-shell lithium battery such as steel shell and aluminum shell.

Suitable for packaging various shapes of aluminum-plastic film, increase product appearance attractiveness; Aluminum-plastic film can be close to aluminum-plastic film, with transparency, beautiful appearance, clean and bright; The packaged aluminum-plastic film has hygiene, cleaning properties, sealed packaging, dust and moisture resistance; Shrink packaging has good shock resistance, impact resistance, and good protection performance; The packaged aluminum-plastic film is compact and fixed, and the small parts will not be swayed in the package;

The thickness of the aluminum-plastic composite film is controlled at 152±3%μm, which has excellent ductility and electrolyte resistance, high composite strength and excellent packaging performance. The special protective layer still has self-healing ability after stretching by stamping, providing stable and long-term protection for the inner layer of the aluminum-plastic film. Aluminum-plastic film adopts special processing technology, so that the product in the shell punching process, the mold surface will not be aluminum-plastic film powder and powder, thus reducing the customer wipe the mold time, while improving the customer production quality.
