Technology for transferring anti-forge laser marker on plastic package

Abstract

A technology for transferring an antiforge laser marker onto plastic package inclues preparing plate roller, gumming, rolling plastic film over the gummed plate roller, compounding laser film, baking, ageing, stripping out laser film, cross chromatography, and applying protecting film. Its advantages are high antiforge power and beautiful appearance.

Description

Technical field [0001] The invention relates to a printing process, in particular to a new process for transferring and printing anti-counterfeit laser marks on packaging plastics. Background technique [0002] Nowadays, there are more and more counterfeit products on the market. In order to prevent counterfeiting, manufacturers generally adopt methods [0003] It is to paste the laser mark on the package. The disadvantage of this method of pasting the laser mark is that it needs to be done manually. The most important thing is that the anti-counterfeiting ability is not strong. In order to solve the above problems, some people have proposed to press the laser mark into the package, and then compound it with plastic film to protect the laser mark, even if the laser mark is between two layers of plastic film , counterfeiters are as easy to counterfeit; in view of the above problems, existing patent applications such as "a new technology for laser holographic hot stamping ima...

Problems solved by technology

[0003] It is to paste the laser mark on the package. The disadvantage of this method of pasting the laser mark is that it needs to be done manually. The most important thing is that the anti-counterfeiting ability is not strong. In order to solve the above problems, some people have proposed to press the laser mark into the package, and then compound it with plastic film to protect the laser mark, even if the laser mark is between two layers of plastic film , counterfeiters are as easy to counterfeit; in view of the above problems, existing patent applications such as "a new technology for laser holographic hot stamping image transfer" published by the Chinese Patent Office on October 1, 1997 with the application number 97100113. Hot-stamping full-suspension embossed film is molded with a metal plate, and the anti-counterfeiting mark is hot-stamped on the printing layer of polypropylene or polyester film for making composite packaging bags by using a special hot stamping machine. The finished packaging bag has anti-counterfeiting marks Sandwiched in the middle of the laminated film, although the anti-counterfeiting technology has improved compared with the original, but the anti-counterfeiting mark is hot stamped with a hot stamping machine and sandwiched in the middle of the laminated film, the anti-counterfeiting grade is still not high, and it is easy for counterfeiters to counterfeit; moreover, the anti-counterfeiting The logo is sandwiched in the middle of the laminated film, protruding from the plastic laminated film, making the plastic packaging unattractive; another patent application for "laser holographic image transfer method" published by the Chinese Patent Office on May 19, 1993 with the application number 92106660.0 , the scheme consists of molding, gluing, hot stamping and other processes. The hot stamping process uses an ordinary printing hot stamping machine with a temperature of 120-170°C and a pressure of 1.5-2.2kg / cm 2 , the flatness of the hot stamping head is 10-50 μm, and the thickness of the PET film is 25 μm. The entire holographic image on the holographic sheet is composed of two-dimensional continuous holographic image units, and the above problems still occur
