Problems solved by technology

Although the film coating process can present a variety of surface effects, the film itself is not easy to degrade, and the film-coated packaging waste is likely to cause environmental pollution
In addition, the production rate of the lamination process is relatively slow, and it is difficult to adapt to large-volume, high-speed printing production

Embodiment 1

[0056] Take a cosmetic packaging box as an example to use screen printing for surface finishing:

[0057] The paper of the cosmetic packaging box is 300g / ㎡ white cardboard. The paper surface of the packaging box is printed with patterns and texts by offset printing process. After printing, it is bronzing and embossed. The paper surface is not printed with varnish or film.

[0058] After the pattern and text are printed, use a screen printing machine to coat a layer of Lishi ink on the paper surface of the cosmetic packaging box. Among them, the components and the weight of the components of Lizan ink are: sodium calcium borosilicate 70g; silicon dioxide 9g; titanium dioxide 9g; iron oxide 11g; tin oxide 1g. Choose 200 mesh mesh for the screen plate used for coating LEISON ink. When coating, avoid the bronzing and concave-convex parts on the surface of the printed matter that do not need to be decorated with Lisan. At the same time, based on the crease line, do not apply Lisan...

Embodiment 2

[0062] Take a cosmetic packaging box as an example to use screen printing for surface finishing:

[0063] The paper of the cosmetic packaging box is 300g / ㎡ white cardboard. The surface of the paper of the packaging box is printed with patterns and texts by gravure printing process. After printing, it is bronzing and embossed.

[0064] After the pattern and text are printed, use a screen printing machine to coat a layer of Lishi ink on the paper surface of the cosmetic packaging box. Among them, the components and weights of the Lishen ink are: sodium calcium borosilicate 54g; silicon dioxide 15g; titanium dioxide 14g; iron oxide 16g; tin oxide 1g. Choose 100 mesh mesh for the screen plate used for coating LEISON ink. When coating, avoid the bronzing and concave-convex parts on the surface of the printed matter that do not need to be decorated with Lisan. At the same time, based on the crease line, do not apply Lisan ink within the width of 2mm on both sides.

[0068] Take a cosmetic packaging box as an example to use screen printing for surface finishing:

[0069] The paper of the cosmetic packaging box is 300g / ㎡ white cardboard. The paper surface of the packaging box is printed with patterns and texts by offset printing process. After printing, it is bronzing and embossed. The paper surface is not printed with varnish or film.

[0070] After the pattern and text are printed, use a screen printing machine to coat a layer of Lishi ink on the paper surface of the cosmetic packaging box. Among them, the components and the weight of the components of Lizan ink are: sodium calcium borosilicate 87g; silicon dioxide 3g; titanium dioxide 4g; iron oxide 6g; tin oxide 0g, no tin oxide is added. Choose 300 mesh mesh for the screen plate used for coating LEISON ink. When coating, avoid the bronzing and concave-convex parts on the surface of the printed matter that do not need to be decorated with Lisan. At the same time, based on the crease li...

Abstract

The invention relates to the field of packaging and printing, in particular to a surface finishing process of a paper packaging box. The invention provides a surface finishing process of a paper packaging box, which uses silk screen printing or gravure printing to coat the surface of the paper of the packaging box with Lishim ink for surface finishing. The invention provides a surface finishing process for paper packaging boxes. Using the finishing process to finish the surface of packaging printed matter, the surface of the packaging box printed with paper materials can produce a sparkling effect, just like sprinkled with a A layer of sequins, showing a shimmering gloss effect under the irradiation of light, makes the packaging of the product more exquisite, and avoids surface scratches caused by production and transportation, and does not affect the molding of the glued box. Moreover, it is environmentally friendly and pollution-free, and can adapt to large-volume, high-speed printing production.

Description

technical field [0001] The invention relates to the field of packaging and printing, in particular to a surface finishing process of a paper packaging box. Background technique [0002] At present, the surface of paper packaging boxes is mainly finished by glazing and film coating to make the surface of the gift box brighter and prevent the graphics and text on the surface of the gift box from being scratched. Among them, the paper packaging box with surface finishing by glazing process mainly presents bright or matte effect in appearance. Although the graphics and text on the surface of the packaging box can be prevented from being scratched to a certain extent after glazing, the surface finishing effect is relatively simple, and only a protective layer is added to the surface of the packaging box, which is difficult to satisfy consumers' desire for unique surface decoration effects. Demand for high-end packaging boxes. Another type of surface finishing process for paper ...
