Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping films, in particular to an anti-counterfeiting hot stamping film. Background Art

[0002] Hot stamping film, also known as anodized aluminum (the term is more commonly used in the printing industry), is a hot stamping material made by applying a coating and vacuum evaporation to a thin film base and then applying a layer of metal foil. Anodized aluminum typically comes in thicknesses of 12, 16, 18, or 20 μm and widths ranging from 500 to 1500 mm. Anodized aluminum foil is produced by applying a release layer and a color layer to a film, vacuum-coating aluminum, and then applying an adhesive layer. Finally, the finished product is rewound.

[0003] Currently, most hot stamping films lack anti-counterfeiting features during production, making them vulnerable to counterfeiting and sale by unscrupulous individuals. Furthermore, during the production process, air trapped within the hot stamping area cannot be directly exhausted from the film, leading to bubbles and leaks due to the lack of airflow during hot stamping over large areas. This can lead to issues such as missed hot stamping, smudged hot stamping, and poor hot stamping adhesion. Therefore, an anti-counterfeiting hot stamping film is urgently needed to address these issues. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the present invention provides an anti-counterfeiting hot stamping film.

[0005] The present invention overcomes the above technical problems by adopting the following technical solutions, specifically:

[0006] An anti-counterfeiting hot stamping film comprises a film body, wherein the film body comprises a base film layer, a release film layer is arranged at the bottom of the base film layer, a holographic information layer is arranged at the bottom of the release film layer, a coloring layer is arranged at the bottom of the holographic information layer, a polyamide layer is arranged at the bottom of the coloring layer, a hot melt adhesive layer is arranged at the bottom of the polyamide layer, and an anti-counterfeiting component is arranged inside the coloring layer.

[0007] As a further solution of the present invention: the top outer wall of the base film layer is provided with first through holes distributed at equal distances, and the tops of the release film layer, holographic information layer, coloring layer, polyamide layer and hot melt adhesive layer are all provided with second through holes distributed at equal distances, and the inner diameter of the second through hole is smaller than the inner diameter of the first through hole.

[0008] As a further solution of the present invention: the thickness of the polyamide layer is 10-15 μm.

[0009] As a further solution of the present invention: the inner diameter of the first through hole is 0.1-15 μm, and the inner diameter of the second through hole is 0.01-0.09 μm.

[0010] As a further solution of the present invention: the anti-counterfeiting component includes an annular groove provided on the top outer wall of the coloring layer, a mounting hole is provided on the bottom inner wall of the annular groove, and a fluorescent block is provided inside the mounting hole.

[0011] As a further solution of the present invention: a laser anti-counterfeiting layer is provided inside the annular groove, and the fluorescent block is located inside the laser anti-counterfeiting layer.

[0012] After adopting the above structure, the utility model has the following advantages compared with the existing technology: by opening a first through hole on the top of the base film layer, and simultaneously opening a second through hole on the top of the release film layer, the holographic information layer, the coloring layer, the polyamide layer and the hot melt adhesive layer, and the inner diameter of the second through hole is smaller than the inner diameter of the first through hole, during the hot stamping process of the film body, the air at the hot stamping position can be directly discharged through the first through hole and the second through hole, effectively avoiding the problems of air bubbles leaking, hot stamping paste and weak hot stamping adhesion caused by the inability to exhaust air during large-area hot stamping, thereby ensuring the quality of hot stamping film production;

[0013] At the same time, the hot stamping film has an anti-counterfeiting component set inside the coloring layer, so that the hot stamping film has an anti-counterfeiting mark, which prevents the hot stamping film from being counterfeited in the market and protects the rights and interests of manufacturers and consumers.
