　　The battery aluminum plastic film of SudaHuicheng EM153(PET) is a kind of four layer composite film ,composed of PET/PA/AL/CPP four kinds of material ,each layer through the adhesive or adhesive resin composite. The PET layer on the surface has certain function of resisting against pollution and corrosion .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 dynamical type soft-packed lithium battery products which have higher requirements.
