Description

Technical Field

[0001] The utility model relates to the technical field of film pasting, in particular to a rainbow transparent laser film pasting. Background Art

[0002] Rainbow film is also called colorful film, dazzling film, fantasy film, laser rainbow film, etc. Rainbow film can be used as a single layer packaging alone, or it can be combined with a variety of materials for application:

[0003] 1. In the glitter powder and gold and silver thread industry, rainbow film can be laminated with PET film for coating and printing, creating a brand new colorful fantasy effect, and processed into gold and silver thread or glitter powder. The product is mainly used in the Christmas gift industry, clothing printing industry, ribbons, etc.

[0004] 2. Paper products industry: After the rainbow film is laminated with coated paper or white cardboard, it can be used alone in gift box packaging, or the composite rainbow film can be further processed and used in anti-counterfeiting packaging, cosmetics or gift packaging;

[0005] 3. Food packaging industry: Rainbow film is mainly used in twist packaging of fruit candies and decorative packaging of craft wedding candies. The rainbow film's own magical effect and transparent characteristics can make the packaged candies and the rainbow film itself appear as one, with excellent visual effects.

[0006] 4. Plastic industry: Rainbow film can be combined with a variety of hard plates for furniture decoration, corner or glass curtain wall decoration, enriching the color of architectural home furnishings;

[0007] 5. Cloth industry: Rainbow film can be compounded with non-woven fabric to make beautiful environmentally friendly shopping bags, or compounded with curtain fabric to make colorful curtains and hanging ornaments with fantasy effects.

[0008] Existing rainbow film products lack toughness and are prone to interlayer peeling, so further improvement is necessary. Utility Model Content

[0009] In order to make up for the deficiencies in the prior art, the utility model provides a rainbow transparent laser film, which has a bright rainbow luster, good toughness, and is not prone to interlayer peeling.

[0010] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0011] A rainbow transparent laser film comprises a transparent substrate layer, a transparent laser layer is provided on the substrate layer, and a transparent rainbow film is hot-stamped on the transparent laser layer; the transparent rainbow film is composed of multiple layers of alternating first and second film layers, wherein the first film layer is methacrylate, and the second film layer is a polymer mixture of polybutylene terephthalate, polybutylene terephthalate elastomer and linear low-density polyethylene.

[0012] The first film layer and the second film layer have the same thickness.

[0013] The transparent rainbow film has 2 to 10 layers.

[0014] The transparent laser layer is provided with a hollow pattern.

[0015] The transparent substrate layer is a PET film with a thickness of 10-25 microns.

[0016] The thickness of the transparent laser layer is 25-35 microns.

[0017] The thickness of the transparent rainbow film is 20-30 microns.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] The rainbow transparent laser film of this utility model is a transparent rainbow film that is hot-stamped on the transparent laser layer, which can improve the overall rainbow gloss of the film and enhance the user experience. Moreover, the rainbow film is composed of multiple layers of thin films arranged alternately and made of different materials, which improves the peeling strength between layers, improves the toughness of the product, and reduces the possibility of breakage during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 The utility model discloses a rainbow transparent laser film structure diagram.

[0021] Among them: 1. transparent substrate layer; 2. transparent laser layer; 3. transparent rainbow film; 31. first thin film layer; 32. second thin film layer. DETAILED DESCRIPTION

[0022] The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Example 1

[0024] like Figure 1 As shown, a rainbow transparent laser film includes a transparent PET substrate layer 1 with a thickness of 10-25 microns, which has advantages such as low surface tension, high transparency, and temperature resistance. A transparent laser layer 2 is provided on substrate layer 1. This transparent laser layer 2 is 25-35 microns thick and has a hollow pattern. The hollow pattern consists of evenly distributed holes. By adjusting the hole density, the light transmittance of the layer can be adjusted.

[0025] A transparent iridescent film 3 is hot-stamped onto the transparent laser layer 2. The iridescent film 3 is composed of alternating layers of first and second film layers 31 and 32. The first film layer 31 is methacrylate, while the second film layer 32 is a polymer blend of polybutylene terephthalate, a polybutylene terephthalate elastomer, and linear low-density polyethylene (see utility model patent CN2543074Y for the preparation method of this polymer blend).

[0026] The transparent iridescent film 3 is made of the aforementioned materials, which improves adhesion between the two layers and enhances the overall strength of the film. The transparent iridescent film 3 has a thickness of 20-30 microns and consists of 2-10 layers. The first film layer 31 and the second film layer 32 are of equal thickness.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
