The film is then wound up using a reel.

[0003] As shown in the prior art with publication number CN216610683U, although the prior art protects the decorative layer through the polyethylene layer and the surface protection layer, the external protective layer can protect the thermal transfer film, thereby preventing the hot melt adhesive layer from solidifying and affecting the subsequent hot melt effect during long-term storage, thereby affecting the bonding effect, and the external protective layer is set to a tear-off structure, so that the external protective layer can be quickly torn off and the internal thermal transfer film can be taken out for use. However, the prior art uses a tearing notch for tearing, and the tearing notch is prone to damage or easy tearing, thereby affecting the connection stability of the external protective layer in the technology. At the same time, the upper and lower separation paper layers in the technical solution are bonded and fixed, and the bonding is prone to not tearing along the predetermined trajectory during the tearing process, thereby affecting the convenience of operation.
