Problems solved by technology

[0002] The traditional positioning laser anti-counterfeiting composite film usually 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.

Embodiment 2

[0036] (embodiment 2, the manufacturing method of positioning laser anti-counterfeiting composite film)

[0037] This embodiment is the manufacturing method of the positioning laser anti-counterfeiting composite film described in Embodiment 1, which has the following steps:

[0038] 1. Prepare the laser transfer film and the printing layer 1 with the laser anti-counterfeiting pattern, the laser transfer film includes the base material and the laser anti-counterfeiting pattern layer 6 arranged on the base material; the printing layer in the present embodiment is a PET layer;

[0039] ② Position printing on one side of the printing layer and dry the ink used for printing, thereby forming a printing area 2 with an ink layer 4 and an adhesive area 3 without an ink layer on the printing layer; when drying the ink, control the drying Baking temperature is 60±5℃;

[0040] ③ On the adhesive area 3 of the printing layer 1, apply glue only on the adhesive area 3 by positioning the glue...

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.
