DETAILED DESCRIPTION

[0024] Based on this, in order to improve the technical problems of lack of anti-counterfeiting features in the related art, the patterns and logos on the thermal transfer film are easy to be copied and counterfeited, which may cause the brand value to be damaged, the embodiments of the present application provide the following solutions.

[0025] For reference Figures 1 to 6 The anti-scratch and anti-fading thermal transfer film with anti-counterfeiting function provided by the embodiments of the present application includes a bottom layer 1, a hot melt adhesive layer 2, a substrate layer 3 and an anti-counterfeiting layer 4. The hot melt adhesive layer 2 is arranged on the bottom layer 1. The substrate layer 3 is arranged on one end of the hot melt adhesive layer 2 away from the bottom layer 1. The anti-counterfeiting layer 4 is arranged on the substrate layer 3.

[0026] In some embodiments, for reference Figures 1 to 5 The anti-counterfeiting layer 4 includes an adhesive layer 41, a hidden anti-counterfeiting layer 42, a temperature change oil film layer 43 and an aluminum foil layer 44. The adhesive layer 41 is arranged on one end of the substrate layer 3 away from the hot melt adhesive layer 2. The hidden anti-counterfeiting layer 42 is arranged in the adhesive layer 41. The temperature change oil film layer 43 is arranged on one end of the hidden anti-counterfeiting layer 42 away from the substrate layer 3. The aluminum foil layer 44 is arranged on one end of the adhesive layer 41 away from the substrate layer 3.

[0027] In this way, multiple anti-counterfeiting technologies are covered at the same time. The adhesive layer 41 not only plays a bonding role, but also serves as part of the anti-counterfeiting, preventing the film from being easily peeled off. The hidden anti-counterfeiting layer 42 provides an invisible or difficult-to-detect anti-counterfeiting feature, such as fluorescent markings or special patterns, which can only be revealed under certain conditions, increasing the difficulty of counterfeiting. The temperature change oil film layer 43 changes color or reveals a specific pattern when the temperature changes, allowing consumers to verify the authenticity of the product through simple touch or heating. The aluminum foil layer 44 provides a physical barrier to prevent the film from being physically damaged or tampered with, while also increasing the aesthetic appeal and durability. By combining multiple anti-counterfeiting technologies, it is difficult for counterfeiters to replicate all levels of anti-counterfeiting features. This structure not only increases the complexity of counterfeiting, but also improves the reliability of the anti-counterfeiting film. The aluminum foil layer 44 and the adhesive layer 41 work together to provide physical protection against damage or tampering. The aluminum foil layer 44 not only provides protection, but also increases the aesthetic appeal of the product, making it more visually appealing. The multi-layer anti-counterfeiting film not only provides anti-counterfeiting features, but also carries a large amount of product information such as production date, batch number and traceability code, facilitating product quality control and product traceability. Once the film is peeled off, the film will automatically be damaged and cannot be restored, effectively preventing the film from being reused. In summary, this multi-layer anti-counterfeiting structure combines multiple anti-counterfeiting technologies to provide comprehensive advantages of high security, easy identification, durability and aesthetic appeal, effectively preventing counterfeiting and tampering, while also carrying a wealth of product information for product quality control and traceability.

[0028] In some embodiments, referring to Figures 1 to 6 , the hot melt adhesive layer 2 is provided with a toughening layer 7, the toughening layer 7 includes carbon fibers 72, glass fibers 73 and toughening agents 71, the carbon fibers 72 are arranged on one end of the substrate layer 3 close to the bottom layer 1, the glass fibers 73 are arranged on one end of the carbon fibers 72 away from the substrate layer 3, the toughening agents 71 are arranged on one end of the substrate layer 3 away from the carbon fibers 72, the surface of the substrate layer 3 close to the carbon fibers 72 is provided with an adhesive 74, the surface of the adhesive 74 away from the substrate layer 3 is provided with an adhesive column 75, the carbon fibers 72 are provided with a groove 76, and the adhesive column 75 is fixedly arranged on the carbon fibers 72 through the groove 76.

[0029] In this way, the carbon fibers 72 have the characteristics of high strength and high modulus, which can significantly improve the tensile strength and bending resistance of the overall structure, prevent the film from being torn or damaged during transportation and use, the glass fibers 73 further enhance the rigidity of the structure, making it more resistant to impact and wear, while providing good dimensional stability, the addition of the toughening agent 71 can improve the brittleness of the carbon fibers 72 and the glass fibers 73, so that they have better flexibility and impact resistance while maintaining high strength, preventing cracks or fractures under extreme conditions, the adhesive 74 ensures that the film can be firmly attached to various surfaces, providing long-lasting adhesion, the adhesive column 75 is fixed on the carbon fibers 72 through the groove 76, further enhancing the adhesion between the film and the substrate, preventing the film from peeling off from the substrate when subjected to external forces, the groove 76 on the carbon fibers 72 is not only designed to fix the adhesive column 75, but also increases the difficulty of tampering with the film, because once the film is opened, the structure of the groove 76 and the adhesive column 75 will be damaged and cannot be restored, the combination of the toughening layer 7 and the adhesive structure makes the film have higher anti-counterfeiting performance, because counterfeiters are difficult to copy such a complex multi-layer structure.

[0030] In some embodiments, referring to Figures 1 to 4 , the anti-counterfeiting layer 4 is further provided with a protective layer 6, the protective layer 6 includes a flame-retardant layer 61, a light-shielding layer 62 and an ultraviolet absorbing layer 63, the ultraviolet absorbing layer 63 is arranged on one end of the aluminum foil layer 44 away from the adhesive layer 41, the light-shielding layer 62 is arranged on one end of the ultraviolet absorbing layer 63 away from the aluminum foil layer 44, and the flame-retardant layer 61 is arranged on one end of the light-shielding layer 62 away from the ultraviolet absorbing layer 63.

[0031] In this way, the fire-retardant layer 61 can effectively prevent the spread of fire and reduce the risk of fire, especially in flammable environments, which can significantly improve the safety of the product. The light-blocking layer 62 can prevent light from penetrating, protecting the internal structure and anti-counterfeiting features of the film from being damaged or disturbed by visible light, ensuring the long-term effectiveness of the anti-counterfeiting function. The ultraviolet-absorbing layer 63 can absorb harmful ultraviolet rays, preventing ultraviolet rays from causing degradation or damage to the internal materials, extending the service life of the film. The introduction of the protective layer 6 increases the multi-layer structure of the film, making it difficult for counterfeiters to replicate all levels of anti-counterfeiting features, further improving the anti-counterfeiting performance. By absorbing ultraviolet rays, the ultraviolet detection equipment is prevented from being used by counterfeiters, increasing the difficulty of anti-counterfeiting verification. In summary, the introduction of the protective layer 6 provides fire-retardant, light-blocking, and ultraviolet protection functions, significantly improving the safety and durability of the anti-counterfeiting film, while also being aesthetically pleasing, multifunctional, and environmentally friendly, effectively protecting the integrity of the product and the brand reputation.

[0032] In some embodiments, referring to Figures 1 to 3 , the protective layer 6 is also provided with a scratch-resistant layer 5, which includes a thermoplastic rubber layer 51, a polyurea coating layer 52, a titanium nitride coating layer 53, and a fluorocarbon coating layer 54. The fluorocarbon coating layer 54 is provided on one end of the fire-retardant layer 61 away from the light-blocking layer 62. The titanium nitride coating layer 53 is provided on one end of the fluorocarbon coating layer 54 away from the fire-retardant layer 61. The polyurea coating layer 52 is provided on one end of the titanium nitride coating layer 53 away from the fluorocarbon coating layer 54. The thermoplastic rubber layer 51 is provided on one end of the polyurea coating layer 52 away from the titanium nitride coating layer 53. The thermoplastic rubber layer 51 is in a raised structure.

[0033] In this way, the thermoplastic rubber layer 51 adopts a raised structure design, which can effectively absorb and disperse external scratches and friction, enhancing the wear resistance of the film surface and preventing the film from being scratched or worn during use. The polyurea coating layer 52 has excellent wear resistance and elasticity, which can further enhance the scratch resistance of the film surface and prolong the service life of the film. The titanium nitride coating layer 53 has extremely high hardness and wear resistance, which can effectively prevent scratches from sharp objects and protect the film surface from damage. The fluorocarbon coating layer 54 has excellent chemical stability and wear resistance, which can provide an additional protective layer to prevent damage to the film from chemical substances and physical scratches.

[0034] In some embodiments, referring to Figures 1 to 2 , the end of the thermoplastic rubber layer 51 away from the polyurea coating layer 52 is provided with a release paper 8, and the release paper 8 is provided with a handle 9.

[0035] In this way, the main function of the release paper 8 is to protect the raised structure of the thermoplastic rubber layer 51 from being abraded, scratched or contaminated during transportation, storage or handling. This ensures that the security film remains in good condition before final use, and the release paper 8 prevents the raised portions of the thermoplastic rubber layer 51 from sticking to other surfaces, ensuring that the film can be easily peeled off and correctly applied when in use. The provision of the pull tab 9 on the release paper 8 allows the user to easily grasp and peel off the release paper 8 without the need for using other tools or struggling to find a peeling point, greatly simplifying the application process of the film and improving the convenience of use.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
