Problems solved by technology

Moreover, when transferring, the glue has poor adhesion to the vacuum coating, and it is often necessary to continue coating a layer of connecting layer outside the vacuum coating to improve it, which not only increases the process flow, but also increases the production cost.

Abstract

The invention relates to a double-layer holographic anti-counterfeiting transfer paper and a production method thereof, and belongs to the technical field of packaging materials. The production method is simple and reliable, the produced double-layer holographic anti-counterfeiting transfer paper has double-layer holographic information and strong anti-counterfeiting property, cold foil stamping UV glue has good adhesion to a vacuum plating layer, and a connecting layer is not used, so the stable period of the above product is greatly prolonged. The product has strong layering sense, allows a BOPP film to be smoothly and completely peeled when the product is used and peeled laterally, has an excellent release property and has a good transfer effect; and a detection result shows that a release layer has very good tolerance to DMF and toluene and resists high temperature, so subsequent layers of the product are convenient to process, and the processed product is flat and smooth, and has the advantages of clear anti-counterfeiting information, long stable time, and easiness in promotion and application.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a double-layer holographic anti-counterfeiting transfer paper and a preparation method thereof. Background technique [0002] The current bronzing process, regardless of the flattening method, or the circular flattening or circular pressing, must be cut into single sheets, which has a long production cycle and low efficiency. For large batches of products, although the use of gravure printing effectively solves the problems of poor stability and low production efficiency, if bronzing is used subsequently, it will seriously restrict production efficiency, increase production costs, and have poor stability. Due to the high temperature and pressure during the bronzing process, some damage to the holographic anti-counterfeiting pattern will be caused, which not only reduces the luster of the product's bronzing pattern, but also greatly weakens the product's anti-counterfe...
