In the current printing and packaging process, in order to ensure that the printed matter will not be rubbed in circulation, in order to improve the waterproof function or improve the product grade, etc., a layer of protection will be made on the surface of the printed matter, some with a layer of varnish, some covered A layer of film, etc. In the glazing process, UV glazing is relatively complicated, and there may be more problems. At present, due to the poor affinity of UV oil and paper, the phenomenon of glue opening often occurs in paste boxes or paste boxes. After coating, the surface tension and surface energy of the film will have different values, sizes or differences under different conditions. In addition, the adhesion of different brands of glue will show different glue, and the phenomenon of glue opening will often occur. . Once the product is delivered to the customer and the glue is opened, there will be a possibility of being fined. These all worry the manufacturers. Some customers will try to purchase imported or domestic high-end paste box glue in order to minimize the above situation. However, if improper storage of chemicals, or other reasons, sometimes glue will appear.

In the traditional process, in order to effectively deal with the phenomenon of gluing, each folder gluer manufacturer is equipped with a edging machine on each type of folder gluer to polish the glue tongue with UV light on the paste part, which effectively solves the problem of gluing.

The coated products are not easy to be polished with a grinding wheel, or most of the coated products are not easy to be polished, and more often use the method of cutting the tooth line, or let the lay-up position when laminating Combined with high-quality glue, it is also more effective, but it is not the best method.

In gluing boxes and gluing boxes, although grinding the glue is more effective in solving the adhesion problem, the following problems still exist:

1. A part of the paper dust and paper powder that were removed during grinding will cause pollution to the environment around the machine and increase the wear of the machine equipment;

2. Because the linear speed direction of the grinding wheel movement is opposite to the product running direction, it will inevitably affect the running speed of some products and reduce the working efficiency;

3. Although the coating is rubbed off, only the UV coating and a small amount of paper surface coating are rubbed off. For high-end medicine boxes and cosmetic boxes and other products, general manufacturers dare not easily use ordinary glue to stick the box. The cost of gluing boxes will not be too low.

Compared with UV products, the situation of film laminating is better than that of UV products. However, the method of laminating the paste can not be used for small box products. The process of cutting the tooth line will also cause process problems and increase the cost of the knife plate.

Polish the surface coating and UV gloss product paste tongue, and the polished product paste tongue can only be polished by a flat paper paste tongue, and if it is a corrugated carton carton, because the surface is uneven Therefore, the effect of polishing is extremely poor.

Comprehensive analysis of the above situation, there is now a technology that solves the above contradiction well, that is, there is no need to grind or grind the surface of the product, and there is no need to use high-cost glue. The big problem:

1. The impact of paper powder and paper wool on the environment and equipment;

Second, polishing affects work efficiency;

3. The product will be glued;

4. The cost of gluing boxes is relatively high.

This technology is low temperature plasma spray technology.

The BSP series surface treatment system uses low-temperature plasma particle flow technology to process the paste box part, remove the organic pollutants from the bonded surface, and perform deep cleaning. Various physical and chemical changes or engravings occur on the surface of the bonded material Etching and roughness, or forming a dense cross-linked layer, or introducing oxygen-containing polar groups, so that the hydrophilicity, adhesion, dyeability, biocompatibility and electrical properties are improved.

After processing the surface of the material under appropriate process conditions, the surface morphology of the material has changed significantly, and a variety of oxygen-containing genes have been introduced to change the surface from non-polar and difficult to sticky to a certain polarity, easy to stick and hydrophilic It improves the surface energy of the bonding surface without causing any damage to the surface, and does not cause peeling of the coating or plating on the surface. It completely changes the physical properties of the surface of the object in the paste box area, greatly improves the surface tension value, and greatly improves the substance. The surface affinity makes the bonding ability of the glue box area and the glue significantly strengthened. Because the treatment system treats the surface with a double physical and chemical reaction, the treated surface performance will not rebound, so after the BSP system treatment After proper bonding, the glue will not open and the bond will be stronger.

Judging from the surface phenomenon after plasma treatment, the surface tension value of the treated UV and film can be as high as 40-60 dynes (depending on the speed and the effective distance between the flame and the object to be treated. ), And the ordinary untreated surface tension value is only not higher than 34 dynes or even lower. In addition, when the surface of the tongue is treated, the flame always comes with an appropriate temperature, and the heat brought by this temperature It is transferred to the surface of the glue tongue, and it has a very good positive effect on improving the initial adhesion performance of the glue box under low temperature conditions in winter.

Therefore, the application of low-temperature plasma particle flow technology in the paste box process directly produces the following benefits: First, the product quality is more stable, and no more glue will be opened; Second, the paste box cost is reduced, and ordinary glue can be used directly under conditions. Cost savings of more than 30%; 3. Directly eliminate the impact of paper powder and paper wool on the environment and equipment; 4. Improve work efficiency. 5. For customers relying on the North, low-temperature plasma processing machines are more effective in winter.

The application objects of low temperature plasma spray technology in printing and packaging are coated products, including BOPP optical film, dumb film, PET film, aluminum film and other plastic products, as well as non-delaminated UV products, such as coated wine boxes. , Industrial product packaging, medicine boxes, cosmetics packaging, electrical packaging, cardboard, corrugated paper and other color boxes can be processed.
