The battery aluminum plastic film of SudaHuicheng EK88 is a kind of three layer composite film ,composed of PA/AL/CPP three kinds of material ,each layer through the adhesive or adhesive resin composite. The surface PA layer (nylon layer) is the protective layer to protect the battery, preventing external force damage and AL layer forming auxiliary role. The middle AL is for blocking layer shape and preventing water intrusion .The inner CPP layer is a heat sealing layer, the main role is to seal adhesive. It’s applicable to soft-packed digital battery products which require thinner aluminum film.
Composition BOPA15/DL3/AL35/PP35
