5 Square Meter Soft Bag Battery Special Aluminum Plastic Film Polymer Lithium Battery Shell for Aluminum Plastic Composite Film (Thickness: 113um, 1)

Aluminum -plastic composite film is a composite material composed of the outer nylon layer (ON layer), the middle aluminum foil layer (AL layer), and the inner layer heat seal (PP layer). Aluminum -plastic film is a key material for soft packaging lithium battery cell packaging. After the single -piece battery is assembled, the battery is sealing with aluminum plastic film, and the aluminum -plastic film plays a role in protecting the content. Compared with packaging materials such as steel shells, aluminum shells, or plastic, aluminum -plastic films have advantages such as light quality, thin thickness, and flexible appearance design. They are widely used in many fields such as 3C consumer electronics, power batteries, and energy storage. Select the specifications of the aluminum plastic film according to the thickness of the battery design: the thickness of the battery ≤3.5mm, select 88um aluminum plastic film; the battery single pit ≤5.0mm/dual pits <8.0mm, select 113um aluminum plastic film; Aluminum plastic film. Aluminum plastic film: 300 mm width
