Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

The embodiment discloses a composite hot stamping film, as shown in fig. 1, which comprises a base layer 1, a stamping layer 2, a first color layer 3, a second color layer 4 and a barrier layer 5 which are sequentially stacked to form a multilayer composite structure.

Wherein, the base layer 1 is a transparent PET film layer, the thickness of which can be generally 10-15 μm and can be properly adjusted according to the requirements of products.

The embossing layer 2 has a thickness of 0.4-0.6 μm, and may be a transparent acrylic coating which will readily form an embossed pattern when heated and which will be revealed from one side when embossed on the other side.

The first color layer 3 and the second color layer 4 may be a composite coating of acrylic resin. The thickness of the first and second color layers 3 and 4 is typically between 0.8 and 1.1 μm. In order to meet different requirements, proper coloring materials can be mixed according to the requirements of the surface color layer to form a surface state with more decorative colors.

The first color layer 3 and the second color layer 4 are sequentially coated on the surface of the base layer 1, after the first color layer 3 is coated, a first laser line is formed by stamping on one side, back to the stamping layer 2, of the first color layer 3 through a hot pressing roller with lines on the surface, and the stamping depth is 1.2-1.4 mu m, so that the first laser line is also pressed into the stamping layer 2, and the first laser line is formed on the stamping layer 2. After the first imprinting, coating a second color layer 4 on the surface of the first color layer 3, imprinting a second laser line on one side of the second color layer 4, which is back to the imprinting layer 2, and staggering the first laser line and the second laser line. The second laser line has larger stamping depth which is about 2.0-2.5 μm, and the stamping penetrates through the second color layer 4 and the first color layer 3 and is pressed into the stamping layer 2, so that the laser line can form an image on the surface of the stamping layer 2 to show. Because the depth of the first laser lines and the depth of the second laser lines have certain difference, and the depths of the bottom surfaces of the first laser lines and the second laser lines are different, different three-dimensional gloss effects are formed on the surface of the film, and the display of difference information is facilitated.

The barrier layer 5 is an aluminum-plated layer and is formed by processing through a vacuum aluminum-plating process, and the thickness of the barrier layer 5 is 0.05-0.06 mu m. Each layer on the surface of the base layer 1 can be coated with the outside through the aluminum coating layer to form the separation of the aluminum coating layer, and the protection effect on the whole film can be achieved.

Further, in order to facilitate the bonding of the film, a hot melt adhesive layer 6 may be additionally disposed on the surface of the film, as shown in fig. 2, the hot melt adhesive layer 6 is laminated and compounded on one side of the barrier layer 5, which is away from the base layer 1, so that the film can be conveniently bonded on the surface of cloth or other products integrally through the hot melt adhesive layer 6, and the composite bonding processing of the film and the surfaces of other products is facilitated.

Specifically, the hot melt adhesive layer 6 can be a hot melt adhesive net film, and the whole hot melt adhesive net film can be compounded on the surface of the film during processing, so that the compounding of the hot melt adhesive layer 6 is facilitated. Alternatively, the hot melt adhesive layer 6 may also be a hot melt coating or a layer of hot melt adhesive particles distributed in dots, or may also form a composite hot melt adhesive layer 6.

Further, as shown in fig. 3, a peelable structure may be disposed between the base layer 1 and the imprinting layer 2, during processing, a release layer 7 is coated on a side of the base layer 1 facing the imprinting layer 2 in advance, and the release layer 7 may be formed of a release layer 7 of a conventional aqueous polyurethane resin, and has a thickness of 0.2-0.4 μm, so that the base layer 1 and the imprinting layer 2 can be peeled from each other. The outer side surface of the aluminum-plated layer can be coated with a thinner gum layer to replace the hot melt adhesive layer 6, and the gum layer can be specifically made of different gum materials according to different surface properties of the pasting surface, and is processed by a conventional coating process.

This kind of membrane can be with its complex bonding on article surfaces such as cloth, can peel off 1 surface of basic unit after bonding because the surface has lost the support of 1 of basic unit for other each layer materials on membrane surface can directly bond on the object surface, and the object can be more laminated to the compound state, also can make the cloth surface more gentle and agreeable.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the fan belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that modifications and embellishments within the scope of the present disclosure may be made by those skilled in the art without departing from the principles of the present disclosure.
