[0034] Specifically, the cursor pattern may be a specific identification pattern, or a pattern hidden in the pattern and / or text of the variable information layer 300, so that the cursor pattern is located at a specific position of the variable information layer 300.

[0035] It is conceivable that, in some embodiments of the present invention, the pattern and / or text of the variable information layer 300 may be a LOGO, an anti-counterfeiting query code or a logistics traceability code, which serves as anti-counterfeiting information to achieve an anti-counterfeiting effect.

[0036] It is conceivable that in some embodiments of the present invention, the back adhesive layer 600 is a hot melt adhesive layer that can adhere to an object when heated.

[0037] It is conceivable that in some embodiments of the present invention, the metal layer 500 is an aluminum-plated layer, a copper-plated layer, a silver-plated layer or a gold-plated layer to enhance the metallic feel and brightness of the graphics on the surface of the hot stamping film to achieve a better holographic display effect.

[0038] It is conceivable that, in some embodiments of the present invention, the area covered by the metal layer 500 corresponds to the pattern and / or text of the variable information layer 300, so as to make the holographic anti-counterfeiting pattern more prominent and conspicuous.

[0039] In some embodiments of the present invention, the metal layer 500 is an aluminum-plated layer, which is disposed on the molded layer 400 by a vacuum evaporation process, and the portion outside the required coverage area of ​​the aluminum-plated layer is cleaned by an aluminum washing process to retain the aluminum-plated area corresponding to the pattern and / or text of the variable information layer 300.

[0040] It is conceivable that, in some embodiments of the present invention, the base film layer 100 is a single film layer or a composite film layer.

[0041] It is conceivable that in some embodiments of the present invention, the base film layer 100 is a PET film layer.

[0042] It is conceivable that the base film layer 100 can also be a PVC base film, a PET+PE combined base film, or the like.

[0043] It is conceivable that in some embodiments of the present invention, the release layer 200 is made of modified acrylic resin, butanone, ethyl ester, etc.

[0044] It is conceivable that, in some embodiments of the present invention, the molding layer 400 is formed by coating a molding agent, molding oil or silicone oil on the release layer 200 and then performing molding.
