Description

Title of the invention: composite anti-counterfeiting film

Technical field

[0001] The present invention relates to a composite anti-counterfeiting film, in particular, a multi-layered nesting effective use space, the composition of the anti-counterfeiting film is small in area, exquisite and beautiful, and has both a laser hidden holographic anti-counterfeiting floating image and a scanning two-dimensional barcode. A dual-function composite security code.

Background technique

[0002] In recent years, the combination of laser holographic anti-counterfeiting technology and printing technology has rapidly developed in the packaging and printing industry. Among them, the holographic pattern has a distinctly colorful rainbow effect, has a decorative effect and has anti-counterfeiting effect, and is widely used in various high-quality trademarks, securities, tobacco, alcohol, food, cosmetics, electronics, high-quality trademarks, securities, Credit cards and high-end crafts.

technical problem

[0003] However, with the continuous development and advancement of technology, traditional laser holographic anti-counterfeiting labels can be easily broken through imitation and lose their anti-counterfeiting function if they have no other encryption aids or further enhancement in holographic molding technology. . To this end, the inventor of the case is responsible for a holographic image recording and holographic image reconstruction method proposed by the company's previous innovation and research, that is, by setting two optical polarizers in the optical path architecture to remove image distortion and "fence effect". Recording a more accurate optical hologram image on the hologram, not only can effectively reduce the size of the recorded full image, but also can generate a larger size of the reconstructed image, effectively enhance the reconstructed image brightness, reconstructed on the holographic film to form The suspended and magnified 3D image greatly improves the quality and observability of reconstructed holographic images, and achieves significant improvements in anti-counterfeiting effects, in line with the increasingly high anti-counterfeiting needs in the market.

[0004] Moreover, in the whole process of actual product circulation and use, it is not only required to use laser tags to provide basic anti-counterfeiting information, but also needs to be matched with two-dimensional bar codes to store product related information and websites, which is convenient and simple. Use the mobile phone to make a photo query, and then provide other functions such as tracking traceability, anti-counterfeiting query, logistics management, and related statistics.

[0005] The prior art Chinese Patent No. 203005987 provides a holographic positioning hot stamping two-dimensional code anti-counterfeit packaging box, characterized in that an anodized aluminum film is stamped on the casing, and the electrochemical aluminum film comprises a base layer and a holographic information layer. The holographic information layer is covered on the base layer, the holographic information layer is hollowed out, and the base layer is provided with a panoramic display two-dimensional code, and the panoramic view displays the two-dimensional code and the holographic information layer hollow portion registration. Thereby, the composition of the anti-counterfeit packaging box has the advantages of convenient use, good anti-counterfeiting effect, and difficulty in being counterfeited. However, as shown in Fig. 6, the actual manufacturing process, because of the laser anti-counterfeit label edge must be reserved for a hollow position, with hot stamping plus two-dimensional bar code, so the laser anti-counterfeit label area will increase the entire, can not effectively streamline and shrink, the product Restrictive, and its two-dimensional bar code configuration 破坏, will destroy the edge of the laser anti-counterfeit label intact, cover part of the anti-counterfeiting pattern, and greatly reduce the aesthetic and pseudo-identification of the entire label, which is its main drawback.
