Release film for die cutting

The utility model discloses a release film for die cutting. The release film comprises a thin film layer, a shock absorption layer, a heat dissipation layer, a release layer and a protective layer, the damping layer, the heat dissipation layer, the thin film layer, the release layer and the protective layer are sequentially laminated from top to bottom. The automobile seat cushion is reasonable in structural design, the damping layer is additionally arranged, the damping effect is achieved, and the possibility that materials are damaged is reduced; a nickel coating, a chromium coating, a graphene film or a heat-conducting silicone grease coating is selected as a heat dissipation layer, heat conduction and heat dissipation effects are achieved, heat accumulation is avoided, and the problem of heat melting of a notch of the composite film is effectively solved; the polystyrene film is selected as the film layer, the brittleness is large, cutting is easy, abrasion of the cutter is reduced, the service life of th
