Problems solved by technology

[0002] Most of the existing nuclear track anti-counterfeiting labels are made of nuclear track anti-counterfeiting film and paper or plastic backing materials. When users check the anti-counterfeiting performance, they need to peel off the nuclear track anti-counterfeiting film and the backing material, and there is a problem of peeling off the film. Difficult problem, at the same time, the existing positioning marks are made by accurate printing, the equipment used is very expensive, the production cost is high, and the process is complicated; therefore, it can only be used to make anti-counterfeiting labels, but cannot realize the packaging of anti-counterfeiting materials and objects The disadvantage of integration, so it is difficult to popularize and apply on many products that require exquisite packaging

Abstract

The invention discloses a packaging-integrated nuclear track anti-counterfeiting disk and a manufacturing method thereof, belonging to the technical field of nuclear track anti-counterfeiting. The nuclear track anti-counterfeiting disk comprises a rubber layer, a release layer, a one-layer nuclear track anti-counterfeiting film label, a laser layer or a metallic coating layer which are sequentially overlapped on a plastic film bottom belt, wherein the laser layer or metallic coating layer is thermally or cold transferred locally or completely on a hot melting gel layer. The one-layer nuclear track anti-counterfeiting film is punched according to the size of an anti-counterfeiting pattern and then waste is eliminated, and a composite material is coiled and trimmed, thus the packaging-integrated nuclear track anti-counterfeiting disk is manufactured. The laser layer can be used as a location marker when industrialized automatic hot-pasting is carried out, a nuclear track anti-counterfeiting film is industrially automatically positioned and thermally transferred to any package material by using the characteristic of hot melting transfer of the transfer laser layer, thus the industrial production integration of the nuclear track anti-counterfeiting film and the package materials is solved, and the nuclear track anti-counterfeiting film has the advantages of attractiveness and wide use and applicability.
