An object of the utility model is to provide a thermoprinting membrane, it sets up the printing ink layer behind transparent medium layer, can not destroy the micro-nano structure in the information layer, radium-shine effect promptly, therefore radium-shine effect's setting does not have the limitation.
In order to achieve the above purpose, the utility model provides a following technical scheme: the hot stamping film comprises a base film layer, a release layer, an information layer, a transparent medium layer and a hot melt adhesive layer which are sequentially arranged from top to bottom, wherein an ink layer is further arranged between the transparent medium layer and the hot melt adhesive layer.
Furthermore, a micro-nano structure used for forming a laser area is arranged on the information layer.
Further, the laser area includes a local laser area.
Further, the laser area includes a through plate laser area.
Further, the laser area comprises a local laser area and a through plate laser area.
Further, the thickness of the base film layer is 10-100 μm.
Further, the thickness of the information layer is 0.1-20 μm.
Further, the transparent medium layer is selected from one of zinc sulfide, titanium dioxide or magnesium fluoride.
Further, the thickness of the transparent medium layer is 30-40 nm.
Further, the base film layer is of a thin film structure and the base film layer is a PET film layer.
Compared with the prior art, the beneficial effects of the utility model reside in that:
