Description

Technical Field

[0001] This utility model relates to the field of laser transfer paper technology, and in particular to a high weather-resistant laser transfer paper anti-counterfeiting structure. Background Technology

[0002] Laser transfer paper is a special type of paper that uses laser transfer technology to transfer complex patterns, text, or logos onto the surface of an item, creating a unique anti-counterfeiting mark that is difficult to replicate. Its core principle is to use laser technology to create complex patterns on the surface of a film material. These patterns are not only visible to the naked eye but also have unique optical effects, making them highly recognizable. Laser transfer paper is generally divided into two types: colored and monochrome. Colored transfer paper has more applications and can be used in many industries such as gifts, home decoration, and T-shirt printing. However, existing laser transfer paper has certain inconveniences when used. First, the existing laser transfer paper uses laser transfer technology to transfer complex patterns, text, or logos onto the surface of the item to form an anti-counterfeiting mark. However, the anti-counterfeiting method is relatively simple and easy to counterfeit. Second, the existing laser transfer paper has poor durability and is easily affected by weather conditions, which can cause the material to fade, change color, crack, powder, and lose strength, resulting in a series of aging phenomena. This causes some inconvenience when using it. To address this, we propose a highly weather-resistant laser transfer paper anti-counterfeiting structure. Utility Model Content

[0003] In view of the existing technology, the anti-counterfeiting method of existing laser transfer paper is simply to transfer complex patterns, text or logos onto the surface of the item through laser transfer technology to form an anti-counterfeiting mark. However, the anti-counterfeiting method is relatively simple and easy to prevent. In addition, the existing laser transfer paper has poor durability and is easily affected by weather conditions, resulting in a series of aging phenomena such as fading, discoloration, cracking, powdering and decreased strength. This utility model provides a high weather-resistant laser transfer paper anti-counterfeiting structure.

[0004] The technical solution adopted by this utility model is: a high weather-resistant laser transfer paper anti-counterfeiting structure, including a base paper and an anti-counterfeiting layer. The anti-counterfeiting layer includes a film, a fluorescent strip, a dividing strip, and an identification mark. The fluorescent strip is located in the middle of the film. The dividing strip and the identification mark are both disposed on the upper outer surface of the fluorescent strip. The identification mark is located on both sides of the dividing strip. An adhesive layer is fixedly connected to the lower outer surface of the base paper. A transfer film layer is disposed on the upper outer surface of the base paper. A refractive medium layer is disposed on the upper outer surface of the transfer film layer. A protective layer is disposed on the upper outer surface of the refractive medium layer. A UV additional layer is disposed on the upper outer surface of the protective layer.

[0005] Furthermore, the protective layer contains a polycarbonate film layer and a polypropylene film layer, with the polypropylene film layer located above the polycarbonate film layer.

[0006] Furthermore, the film and the fluorescent strip are integrally formed, and the identification mark is a triangular structure.

[0007] Furthermore, the width of the fluorescent strip is 0.3 cm, and the spacing between the identification marks is 0.5 cm.

[0008] Furthermore, the thickness of the protective layer is 0.08 cm, and the thickness of both the polycarbonate film layer and the polypropylene film layer is 0.03 cm.

[0009] The beneficial effects of this utility model are: 1. In this utility model, the anti-counterfeiting layer can emit light through the fluorescent strip at night or in low light conditions, making it difficult to detect during the day or in strong light conditions. In addition, the identification marks on both sides of the strip are distributed at specific intervals, making it difficult to counterfeit. This can improve the anti-counterfeiting effect of existing laser transfer paper and enhance the anti-counterfeiting identification.

[0010] 2. In this utility model, the protective layer can improve the weather resistance of the laser transfer paper through the polycarbonate film layer and the polypropylene film layer, which can reduce the aging phenomena such as fading, discoloration, cracking, powdering and strength reduction caused by the influence of climatic conditions.

[0015] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described below.

[0016] To address the problems existing in the background technology, this application proposes the following technical solution: a high weather-resistant laser transfer paper anti-counterfeiting structure.

[0017] The specific technical solution includes a base paper 1 and an anti-counterfeiting layer 4. The anti-counterfeiting layer 4 includes a film 41, a fluorescent strip 42, a dividing strip 43, and an identification mark 44. The fluorescent strip 42 is located in the middle of the film 41. The dividing strip 43 and the identification mark 44 are both set on the upper outer surface of the fluorescent strip 42. The identification mark 44 is located on both sides of the dividing strip 43. An adhesive layer 3 is fixedly connected to the lower outer surface of the base paper 1. A transfer film layer 5 is set on the upper outer surface of the base paper 1. A refractive medium layer 6 is set on the upper outer surface of the transfer film layer 5. A protective layer 7 is set on the upper outer surface of the refractive medium layer 6. A UV additional layer 8 is set on the upper outer surface of the protective layer 7. When in use, the anti-counterfeiting layer 4 can emit light through the fluorescent strip 42 at night or in low light conditions, making it difficult to detect during the day or in strong light conditions. In addition, when in use, the identification marks 44 on both sides of the dividing strip 43 are distributed at a specific interval, making it difficult to counterfeit. This can improve the anti-counterfeiting effect of existing laser transfer paper and enhance the anti-counterfeiting identification rate.

[0018] Furthermore, the film 41 and the fluorescent strip 42 are integrally formed, the identification mark 44 is a triangular structure, and the fluorescent strip 42 can emit light at night or in low light conditions, which can play an anti-counterfeiting role.

[0019] Furthermore, the fluorescent strip 42 is 0.3 cm wide, and the spacing between the identification marks 44 is 0.5 cm. The identification marks 44 can be distributed at specified intervals, providing high anti-counterfeiting protection during use.

[0020] Reference Figure 3 As shown, the protective layer 7 has a polycarbonate film layer 9 and a polypropylene film layer 10 inside. The polypropylene film layer 10 is located above the polycarbonate film layer 9. When in use, the protective layer 7 can improve the weather resistance of the laser transfer paper through the polycarbonate film layer 9 and the polypropylene film layer 10, which can reduce the aging phenomena such as fading, discoloration, cracking, powdering and strength reduction of the laser transfer paper caused by climatic conditions.

[0021] Furthermore, the protective layer 7 has a thickness of 0.08 cm, and the polycarbonate film layer 9 and the polypropylene film layer 10 both have a thickness of 0.03 cm. The polycarbonate film layer 9 has good UV resistance and can maintain its physical properties for a long time in outdoor environments. Even under prolonged direct sunlight, it will not easily turn yellow or become brittle. The polypropylene film layer 10 has good humidity resistance and can maintain good stability in environments with large temperature changes, effectively preventing corrosion and performance degradation caused by moisture.

[0022] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: During use, the film 41 is fixed on the vacuum-plated aluminum layer 2. The fluorescent strip 42 in the middle of the film 41 can emit light at night or in low light conditions, but is not easily noticed during the day or in strong light conditions. In addition, the identification marks 44 on both sides of the strip 43 are distributed at specific intervals, making it difficult to counterfeit. This can improve the anti-counterfeiting effect of existing laser transfer paper and enhance the anti-counterfeiting identification. The protective layer 7 is located below the UV-additional layer 8 during use. Through the polycarbonate film layer 9 and polypropylene film layer 10 inside, it can improve the weather resistance of the laser transfer paper and reduce a series of aging phenomena such as fading, discoloration, cracking, powdering and strength reduction caused by climatic conditions. The polycarbonate film layer 9 has good UV resistance and can maintain its physical properties for a long time in outdoor environments. Even under prolonged direct sunlight, it will not easily turn yellow or become brittle. The polypropylene film layer 10 has good humidity resistance and can maintain good stability in environments with large temperature changes, which can effectively prevent corrosion and performance degradation caused by moisture.
