Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat transfer film technology, specifically a heat transfer film with anti-counterfeiting markings. Background Technology
[0002] Heat transfer film is a medium material used in heat transfer printing to achieve surface decoration. It consists of a polyethylene backing paper, a decorative layer, a protective layer, a release layer, and a hot melt adhesive layer. It transfers patterns onto the surface of building materials, furniture, and other substrates through heating and pressure, forming a wear-resistant and light-resistant decorative layer. The process requires control of temperature, pressure, and speed to ensure strong adhesion and prevent oxidation and deformation.
[0003] Traditional heat transfer films have limitations due to the fragility of the protective layer and difficulty in adapting to curved surfaces. A novel heat transfer film patent proposed in 2024 employs a post-dual curing technology, optimizing the material ratio of the carrier layer and protective layer. It uses ultraviolet light or a heat source to cure the decorative layer and adhesive layer in stages, improving stretchability to meet the requirements of curved surface transfer. This technology uses a composite resin containing free radicals and cationic photoinitiators, balancing production economics with improved film properties.
[0004] When using existing anti-counterfeiting heat transfer films, the anti-counterfeiting pattern layer is prone to damage and peeling off after prolonged use, which damages the anti-counterfeiting film layer and thus affects the anti-counterfeiting effect of the heat transfer film. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a heat transfer film with anti-counterfeiting mark. By setting an anti-counterfeiting pattern film layer, an electronic tag, a sealing layer and a lower isolation film layer, the electronic tag set on the lower side of the anti-counterfeiting pattern film layer has an electronic anti-counterfeiting function. When the anti-counterfeiting pattern layer is damaged and falls off, the electronic tag can play an anti-counterfeiting role as an anti-counterfeiting structure, ensuring the anti-counterfeiting effect of the heat transfer film and effectively solving the problems in the background technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat transfer film with anti-counterfeiting markings, comprising an upper release paper, a protective film layer disposed on the lower side of the upper release paper, an anti-counterfeiting layer disposed on the lower side of the protective film layer, the anti-counterfeiting layer comprising an anti-counterfeiting pattern film layer, a sealing layer disposed on the lower side of the anti-counterfeiting pattern film layer, an electronic tag disposed within the sealing layer, and a lower isolation film layer disposed on the lower side of the sealing layer.
[0007] Furthermore, a separating layer is provided on the lower side of the anti-counterfeiting layer, and a pattern layer is provided on the lower side of the separating layer.
[0008] Furthermore, a base layer is disposed on the underside of the pattern layer, and a hot melt adhesive layer is disposed on the underside of the base layer.
[0009] Furthermore, the upper release paper is connected to the protective film layer by electrostatic adsorption, and the protective film layer is bonded to the anti-counterfeiting layer.
[0010] Furthermore, the anti-counterfeiting layer is bonded to the separating layer, and the separating layer is bonded to the pattern layer.
[0011] Furthermore, the pattern layer is bonded to the base layer, and the thickness of the hot melt adhesive layer is twice the thickness of the base layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of an anti-counterfeiting pattern film layer, an electronic tag, a sealing layer, and a lower isolation film layer, enables the electronic tag set on the lower side of the anti-counterfeiting pattern film layer to have an electronic anti-counterfeiting function. When the anti-counterfeiting pattern layer is damaged and falls off, the electronic tag can serve as an anti-counterfeiting structure to ensure the anti-counterfeiting effect of the heat transfer film.
