Aluminum plastic film and battery

The aluminum-plastic film comprises a nylon layer, an aluminum layer and a CPP (casting polypropylene) film layer, and a first identification symbol is printed on the inner side surface of the nylon layer in a jet printing manner; the aluminum layer is attached to the inner side surface of the nylon layer; the CPP film layer is attached to the side face, away from the nylon layer, of the aluminum layer. According to the aluminum-plastic film and the battery, the identification symbols such as Logo, two-dimensional codes and the like are printed on the inner side surface of the nylon layer or the outer side surface of the aluminum layer in a jet printing manner, so that aluminum-plastic film manufacturers can be quickly identified, and the aluminum-plastic film and the battery can be used for different production lines or different models by printing the digital identification symbol content in the aluminum-plastic film in a jet printing manner; therefore, production lines and battery models can be quickly ide
