· Product description:

Substrate: Polyester film
Rubber system: synthetic rubber hot melt adhesive
Color: Translucent
Specifications:(530mm) width can be cut (50M, 100M) length optional

· Product characteristics:

The ultra-thin polyester film is used as the base material, which has high flatness and good adherence. Different adhesive systems are coated on both sides, which is easy to roll and paste. After hot pressing, the peeling force can be greatly improved, which helps to improve the passing rate of lithium battery drop test, improve product stability and meet the demand of automatic production.

· Product Application:

Specially used for bonding between bare cell of soft pack battery and aluminum plastic film.
