The packaging product is also gradually changed into an aluminum plastic flexible package from a hard aluminum shell and the like, and the flexible package is compounded by high-barrier aluminum foil and a plastic film with chemical resistance, heat resistance and flexibility. From 3C lithium batteries to lithium batteries for power automobiles, the flexible packaging material has huge market prospects and has great demand.
At present, the soft package material aluminum plastic film of the lithium battery consists of PA, aluminum foil and CPP, and is a soft packaging material. However, the outer layer is very easily scratched and torn due to the softness. In the process of manufacturing the aluminum-plastic film, foreign matters on the guide roller can influence the aluminum-plastic film to form concave-convex points, so that the yield is reduced. Before the lithium battery is prepared, the aluminum-plastic film needs to be deeply punched and formed, however, if scratches or concave-convex points exist on the surface of the aluminum-plastic film, the forming cannot be carried out, otherwise, the safety of the lithium battery is affected, and the scratched aluminum-plastic film can only be scrapped, so that the utility model provides the novel scratch-resistant aluminum-plastic film.
