Embodiment Construction
[0014] Such as figure 1 As shown, the structure of the four-layer white cardboard with an anti-counterfeiting layer includes a surface layer 1, a lining layer 11, a core layer 12, a bottom layer 13 and an anti-counterfeiting coating 14, and the anti-counterfeiting coating 14 is a textured color coating, and the color The coating layer is a water-based anti-counterfeiting coating, which is usually set on the back of the white cardboard. The color coating is coated with a grooved scraper bar 2. After coating, the white cardboard has a textured anti-counterfeiting color coating , simple in structure and suitable for mass production.
[0015] Such as figure 2 As shown, there are grooves 21 on the scraping rod 2 used, and the grooves 21 on the scraping rod 2 can be set into a regular structure as required, so that it is easy to leave regular patterns in the process of white cardboard coating. texture. Its manufacturing process is:

The invention relates to an anti-counterfeiting coating white card paper and a production process thereof, which mainly solve the problems of high cost and complicated process of common white card paper. The anti-counterfeiting coating white card paper comprises raw paper of the white card paper, wherein the raw paper of the white card paper is provided with an aqueous anti-counterfeiting color coating layer; the color coating layer is provided with textures; and the raw paper is provided with at least three layers of structures, including a surface layer, a core layer and a bottom layer. Theproduction process comprises the following steps: coating with a scraping bar in the process of coating, wherein the scraping bar has a groove structure; adding pigment into paint; and using the scraping bar to coat one surface with the pigment so that the white card paper has the dual anti-counterfeiting structure of anti-counterfeiting textures and the anti-counterfeiting color coating layer. The white card paper has more favorable anti-counterfeiting effect, low cost and simple operation and is difficult to simulate, and the paint uses a non-toxic and harmless material, can be used for packaging foods and medicines and has wide application range.
Description
technical field [0001] The invention relates to a white cardboard and its production process, in particular to a coated white cardboard for anti-counterfeiting and its production process. Background technique [0002] At present, known anti-counterfeiting paper generally adopts technologies such as watermark, safety thread and anti-counterfeiting fiber. Watermark anti-counterfeiting refers to the use of watermark rollers or engraved circular cages to make watermark patterns during the paper production process. This method needs to invest a lot of money to transform the paper machine, and it is easy to be imitated. Security thread anti-counterfeiting refers to spraying metal wires into the forming part of papermaking. Although this method has a good anti-counterfeiting effect, the equipment is complicated and the investment is large. Common anti-counterfeiting fibers include fluorescent fibers and colored fibers. Fluorescent fiber anti-counterfeiting refers to adding fluor...
