PET film coated with heat melting adhesive; used for improving the cell DROP performance by bonding jelly roll and packing foil.
The product has excellent resistance to lithium battery electrolyte, electrolyte immersion, the tape retention force unchanged, not with the electrolyte due to swelling and lead to degradation of bonding strength. At the same time the product has a suitable initial bonding strength, easy to automate the operation of the machine.
The product is widely used in lithium battery cell tail package, bare cell bottom bonding.
