Locating laser anti-counterfeiting compound film and manufacturing method thereof

Abstract

The invention discloses a positioning laser anti-fake complex film and a production method thereof. The complex film is provided with a printing bearing layer which consists of a printing area and a gluing area, a printing ink layer is printed on the printing area, a first gluing layer is coated on the gluing area and adhered with a laser anti-fake layer, and a second gluing layer and a protective layer are arranged on the printing ink layer and the laser anti-fake layer. The production method of the positioning laser anti-fake complex film includes the steps of: 1) preparing a laser transfer film and the printing bearing layer; 2) printing the printing ink layer on the printing bearing layer; 3) forming the first gluing layer on the gluing area; 4) compounding the printing bearing layer and the laser transfer film by hot pressing; 5) carrying out heat-preservation-type curing treatment; 6) peeling off operation, i.e., peeling off the base material in the laser transfer film; 7) coating a layer of gulewater on the blank of the complex film to form the second gluing layer; and 8) obtaining the finished product by compounding the blank of the complex film and the protective film by hot pressing. The product can effectively protect the laser anti-fake layer and prevent the falling off of the laser anti-fake layer, and the method has higher yield.

Description

technical field [0001] The invention belongs to the technical field of plastic packaging materials, and in particular relates to a positioning laser anti-counterfeiting composite film and a manufacturing method thereof. Background technique [0002] The traditional positioning laser anti-counterfeiting composite film generally puts the laser anti-counterfeiting layer on the outer layer, which is easy to fall off due to friction. [0003] Since the composite layer is cooled and the film is directly peeled off after the pressurized lamination, due to its short time, for the adhesive in the adhesive layer, it is not suitable for the adhesive combination of the laser transfer film that removes the base film. It will take a long time to fully solidify. If the film is peeled off directly after the composite layer is cooled, the quality of the finished product after peeling off the film cannot be fully guaranteed, and waste products are likely to be generated.

[0003] Since the composite layer is cooled and the film is directly peeled off after the pressurized lamination, due to its short time, for the adhesive in the adhesive layer, it is not suitable for the adhesive combination of the laser transfer film that removes the base film. It will take a long time to fully solidify. If the film is peeled off directly after the composite layer is cooled, the quality of the finished product after peeling off the film cannot be fully guaranteed, and waste products are likely to be generated.
