The metal composite film proposed by the present invention comprises a metal layer, an inner layer adhesive layer, a hot-melting grease layer, an outer layer adhesive layer and an outer layer, the outer layer is arranged on one side of the metal layer, and the The thermal fusion resin layer is arranged on the other side of the metal layer, the inner adhesive layer is arranged between the metal layer and the first thermal fusion resin layer, and the outer adhesive layer is arranged on the outer layer Between the metal layer and the metal layer, an anti-corrosion layer may be provided on both sides of the metal layer, and the thermal fusion resin layer is a layer structure formed by slug-forging fluorine resin or random copolymerization of other polar groups. The metal composite film has high heat-sealing strength and good tolerance when forming a soft pack battery. |
