Example Embodiment

[0032] (Example 1. Positioning laser anti-counterfeiting composite film)

[0033] figure 1 with figure 2 Shows a specific embodiment of the product of the present invention, where figure 1 It is a schematic diagram of the first structure of the product of the present invention; figure 2 Yes figure 1 The cross-sectional view of the positioning laser anti-counterfeiting composite film along the line A-A is shown.

[0034] see figure 1 This embodiment is a positioning laser anti-counterfeiting composite film, which has a printing layer 1. The printing layer 1 is provided with a printing area 2 and an adhesive area 3, and the printing area 2 is printed with a preset ink text layer or The ink pattern layer 4, the first adhesive layer 5 is coated on the adhesive area 3, and the laser anti-counterfeiting layer 6 is adhered on the first adhesive layer 5; the ink layer 4 and the laser on the printing layer A second adhesive layer 7 is further provided on the anti-counterfeiting layer ...

Example Embodiment

[0036] (Embodiment 2, 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, and has the following steps:

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

[0039] ② Position the 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] ③In the adhesive area 3 of the printing layer 1, the glue is applied only on the adhesive area 3 by positioning the glue, and then the glue is dr...

Example

[0049] (Embodiment 3 to Embodiment 4, manufacturing method of positioning laser anti-counterfeiting composite film)

[0050] Embodiment 3 and Embodiment 4 are basically the same as Embodiment 2, except that the process parameters in the process steps are different, and the specific process parameters in each embodiment can be referred to Table 1.

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.
