Laser holographic mirror anti-counterfeiting film pressure casting process

Abstract

The invention relates to a laser holographic mirror anti-counterfeiting film pressure casting process. The process is characterized by firstly, mold-pressing a metallic nickel plate on which laser anti-counterfeiting pattern information is carved and a BOPP (biaxially oriented polypropylene) film into a roll BOPP mask with pattern information, secondly, coating a layer of UV (ultraviolet) medium varnish on printing paper, film-pressing and casting the printing paper with the BOPP mask in a non-solid state, then carrying out irradiation with a UV light source to instantly cure the BOPP mask, and after curing, stripping and rolling the BOPP film with a stripping machine. The process has the following beneficial effects: the package and production costs can be effectively lowered; the preparation process is simple; the color is bright and the stereoscopic sense is strong; and in particular, as the laser holographic mirror anti-counterfeiting technology is directly realized on the common paper, the produced package is high in anti-counterfeiting grade, is not easy to counterfeit, is beautiful and is far better than the prior art in practicability, environment friendliness, anti-counterfeiting property, economy and the like.

Description

technical field [0001] The invention relates to the technical field of packaging and printing, in particular to a laser holographic mirror surface anti-counterfeiting film die-casting process. Background technique [0002] At present, the printing and packaging measurement standards are: practicability, environmental protection, anti-counterfeiting, economy, aesthetics, etc., which is also a research topic that the printing and packaging industry is committed to. From the perspective of my country's printing and packaging market, usually in packaging products, in order to improve the packaging effect and grade, laser transfer film, laser anodized aluminum and other materials are used to decorate the packaging box, so that the appearance of the packaging box can achieve the laser transparent mirror effect. . However, there are advantages and disadvantages. First of all, a large amount of metal aluminum, BOPP film, peeling glue and colloid are still used in the production ...

AI Technical Summary

Problems solved by technology

However, there are advantages and disadvantages. First of all, a large amount of metal aluminum, BOPP film, peeling glue and colloid are still used in the production process of laser transfer film and laser anodized aluminum, resulting in waste of resources, serious pollution of the natural environment, and harm to human health. Certain hazards; secondly, the production cost of laser transfer film and anodized aluminum is relatively high, especially in the use of such chemical products in wine packaging, the price is higher, which leads to lower and lower profits of packaging and printing products; thirdly, traditional laser Wine boxes, gift boxes, etc. produced by transfer film, laser anodized aluminum, etc., the post-press processing technology is very cumbersome, the transfer accuracy is not high, the content is not rich enough, the production efficiency is low, and the laser and anti-counterfeiting effects have great limitations.
