Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping films, in particular to an anti-counterfeiting hot stamping film with a code. Background Art

[0002] Hot stamping film combines laser holographic anodized aluminum film with hot stamping technology to create a vibrant, colorful laser holographic logo and three-dimensional patterned anti-counterfeiting mark on the surface of printed materials. This technology can add laser encryption and a back-tear barrier, and is used to prevent counterfeiting on documents, cards, bills, trademarks, etc.

[0003] However, the anti-counterfeiting identification of existing anti-counterfeiting hot stamping films is not simple enough. Although some optical anti-counterfeiting marks are not easy to counterfeit, they are also difficult to identify and require the use of special techniques or tools. If the identification of anti-counterfeiting hot stamping films is too complicated and inconvenient to master, even the best anti-counterfeiting marks will lose their function. Moreover, the existing anti-counterfeiting hot stamping films do not have positioning parts, which makes the entire anti-counterfeiting hot stamping film relatively soft, making it inconvenient to operate during hot stamping and having poor practicality.
