Abstract

The invention discloses an anti-counterfeiting packaging integrated preparation process. The anti-counterfeiting packaging integrated preparation process comprises the following steps of (1) preparation of raw materials, (2) corona treatment, (3) unwinding, (4) release agent coating, (5) ink coating and (6) coating adhesive coating. The anti-counterfeiting packaging integrated preparation processhas small chemical reflection on a substrate thin-film, is not influenced by the thickness of the substrate thin-film on the surface smoothness, improves the surface tension and roughness of the thin-film, and is beneficial to the adhesion of ink and an adhesive. Under the condition of not affecting printing requirements, the release anti-counterfeiting technology with the anti-counterfeiting function can be achieved, local coating can be flexibly applied according to anti-counterfeiting design requirements, the imitation difficulty is increased, a release anti-counterfeiting product with no difference on the surface can be printed, and the anti-counterfeiting packaging integrated preparation process has the characteristics of high flatness, strong tightness and the like.

Description

technical field [0001] The invention relates to the field of packaging materials, more specifically, an integrated preparation process for anti-counterfeiting packaging. Background technique [0002] Substrate film is the main substrate of gravure printing. Commonly used plastic films are polyethylene, polypropylene, polyvinyl chloride, etc. Because the surface of the plastic film is smooth and the performance of adhering ink is poor, the surface of the film should be treated before printing. Generally, corona treatment is used. This method is to pass the plastic film through two electrodes, and use high-frequency oscillating pulses to force the air to ionize to generate a discharge phenomenon to form a corona. Free oxygen atoms combine with oxygen molecules to generate ozone, which makes the surface of the film form Some strong groups and "burrs" invisible to the naked eye increase the surface tension and roughness of the film, which is conducive to the adhesion of ink an...
