Description

Technical Field

[0001] The utility model belongs to the technical field of laser films, and particularly relates to a multi-color hot stamping positioning laser film. Background Art

[0002] The multi-color hot stamping laser film technology is a decorative technology that creates a three-dimensional effect and gloss by adding multiple colors, hot stamping, and laser film to the surface of an object. Its core is to use high temperature and pressure to fuse multiple hot stamping and laser films of different colors together to form a single surface coating. This technology can be used on many different types of surfaces, including paper, plastic, metal, wood, etc., making them present a colorful effect. The multi-color hot stamping laser film has been widely used in the packaging and printing industries, providing a strong visual effect for the brand and enhancing the high-end, luxurious, and quality feeling of the product.

[0003] In the prior art, the application number 202222311499.0 discloses a hot melt adhesive composite laser film, which relates to the technical field of laser films. The key points of its technical solution are: including a base layer, a release layer, a laser film layer, and a hot melt adhesive layer stacked in sequence. The thickness of the release layer is 0.2 - 0.4μm, and the hot melt adhesive layer is a hot melt adhesive film, and the hot melt adhesive film is bonded to the laser film layer. One side of its laser composite film forms a film-like support with the hot melt adhesive film layer and can be directly hot-pressed and bonded, facilitating the composite bonding of the laser film layer. And a peelable base layer is provided on the other surface of the composite laser film to protect the surface of the laser film layer.

[0004] However, since the release layer is generally coated on the base layer to ensure that the base layer and other layer structures on the laser film can be smoothly separated under the conditions of heating and pressing. However, because the release layer is coated on the base layer and has a certain viscosity, it is possible that the release layer will tear and partially remain on other layer structures of the laser film after the base layer is lifted. Therefore, in order to ensure that the release layer can be completely separated when the base layer is separated, a multi-color hot stamping positioning laser film is proposed. Summary of the Utility Model

[0005] In order to solve the problem in the prior art that the release layer may be torn and partially remain on other layer structures of the laser film after the base layer is lifted, the utility model provides a multi-color hot stamping positioning laser film.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A multi-color hot stamping positioning laser film of the utility model includes a release layer and a base layer. The release layer is arranged inside the base layer, and a fiber layer is adhered to one side of the base layer close to the release layer. The fiber layer is used to improve the separation integrity of the release layer.

[0008] Further, the fiber layer is a diamond-shaped fiber mesh.

[0009] Further, the diamond-shaped fiber mesh forms a number of regular protrusions based on its plane, and a number of the protrusions are suspended on the base layer.

[0010] Further, the release layer is coated on the base layer, and the release layer penetrates into the protrusions of the diamond-shaped fiber mesh.

[0011] Further, it further includes an adhesive layer, an aluminized layer, a color printing positioning layer, and a wear-resistant resin layer. The adhesive layer, aluminized layer, color printing positioning layer, wear-resistant resin layer, and release layer are arranged in sequence from top to bottom on the base layer.

[0012] Further, a number of positioning points are printed on the color printing positioning layer, and a number of the positioning points form a rectangular array on the color printing positioning layer for positioning.

[0013] The beneficial effects of the present utility model are as follows: By providing a fiber layer on the base layer, the fiber layer adheres to the base layer. Since there are a number of fibers stacked on each other on the general fiber layer, and the diameter of each limiting fiber is small, when the release layer is coated on the base layer and the release layer is separated from the base layer during use, the contact area between the fiber layer and the release layer can be increased, and there are a number of dispersed fibers on the fiber layer, which can keep the integrity of the release layer after combining with the release layer, and avoid causing part of the release layer to still adhere to other layer structures on the laser film when separated through the base layer.

[0019] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, with reference to the accompanying drawings and preferred embodiments, describe in detail the specific embodiments, structures, features, and effects according to the present utility model.

[0020] As shown Figures 1-3 in the figure, a multi-color hot stamping positioning laser film of the present utility model includes a release layer 2 and a base layer 1. The release layer 2 is arranged inside the base layer 1. A fiber layer 3 is adhered to one side of the base layer 1 close to the release layer 2. The fiber layer 3 is used to improve the separation integrity of the release layer 2;

[0021] Since the release layer 2 is generally coated on the base layer to ensure that the base layer 1 can be smoothly separated from other layer structures on the laser film under the conditions of heating and pressing. However, because the release layer 2 is coated on the base layer and has a certain viscosity, it is possible that the release layer 2 is torn and partially remains on other layer structures of the laser film after the base layer 1 is lifted. Therefore, in order to ensure that the release layer 2 can be completely separated when the base layer 1 is separated, a fiber layer 3 is provided on the base layer 1. The fiber layer 3 is adhered to the base layer 1. Since there are generally several mutually stacked fibers on the fiber layer 3 and the diameter of each fiber is small, when the release layer 2 is coated on the base layer 1 and the release layer 2 is separated from the base layer 1 during use, the contact area between the fiber layer 3 and the release layer 2 can be increased, and there are several dispersed fibers on the fiber layer 3, which can keep the integrity of the release layer 2 after combining with the release layer 2, and avoid the problem that part of the release layer 2 still adheres to other layer structures on the laser film when separated through the base layer 1, resulting in difficult cleaning or poor aesthetics.

[0022] In an embodiment, the fiber layer 3 is a diamond fiber mesh 21. The diamond fiber mesh 21 means that the mesh holes of the fiber mesh are diamond-shaped. Since the thickness of each layer structure on the laser film is very small, basically all at the micron level, both the release layer 2 and the diamond fiber mesh 21 are at the micron level. Through the multiple surrounding and closed mesh holes on the diamond fiber mesh 21, when the release layer 2 is a relatively thin liquid layer, after the release layer 2 is combined with the fiber layer 3, there is a certain tension in the mesh holes of the release layer 2. Under the action of the tension of each mesh hole, the entire release layer 2 can be completely separated from other layer structures on the laser film, avoiding partial residue caused by tearing of the release layer 2.

[0023] Further, several regular protrusions are formed on the diamond fiber mesh 21 based on its plane. The several protrusions are suspended above the base layer 1, and the several protrusions form a wavy shape, that is, the periphery of each protrusion is recessed in the opposite direction, and the protrusions and the recesses are arranged at intervals. The bottom surface of the recess of the diamond fiber mesh 21 adheres to the base layer 1, while the protrusions are combined with the release layer 2. That is, on the one hand, the release layer 2 is attached to the base layer 1, and on the other hand, since the diamond fiber mesh 21 is a hollow structure, the combination of the diamond fiber mesh 21 and the release layer 2 can increase the force-bearing area and provide a greater separation force. Moreover, by contacting the release layer 2 at multiple positions on each protrusion, it is ensured that there is a force application point when the release layer 2 near each protrusion is separated, avoiding tearing of the release layer 2.

[0024] In an embodiment, it further includes an adhesive layer 7, an aluminized layer 6, a color printing positioning layer 5, and a wear-resistant resin layer 4. The adhesive layer 7, the aluminized layer 6, the color printing positioning layer 5, the wear-resistant resin layer 4, and the release layer 2 are arranged in sequence from top to bottom on the base layer 1. The adhesive layer 7 of the laser film is the key part for adhering the film to the target object. During the hot stamping process, the adhesive layer 7 softens after being heated and adheres to the target object, so that the laser film is tightly combined with the target object and does not fall off or deform under high-temperature conditions; the aluminized layer 6 is the key part of the laser hot stamping film, and its main function is to enhance light reflection and change the color of the coloring layer to make it show a metallic luster. The aluminized layer 6 makes the laser film have a unique gloss and brightness, enhancing the overall visual effect; the color printing positioning layer 5 is the main decorative layer of the laser hot stamping film. Through processes such as die stamping and printing, various patterns, characters, and colors can be formed on the color printing positioning layer 5, providing rich visual effects and aesthetic feelings for the laser film. At the same time, by printing positioning marks on the color printing positioning layer 5, it can play an auxiliary positioning role in positioning and pasting during use; the wear-resistant resin layer 4 provides excellent wear resistance for the laser film. It can prevent the laser film from being scratched or worn during transportation, storage, and use, maintaining its good appearance and effect.

[0025] Further, several positioning points 51 are printed on the color printing positioning layer 5, and the several positioning points 51 form a rectangular array on the color printing positioning layer 5 for positioning.

[0026] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes, but as long as it does not depart from the technical content of the present invention, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
