The packaging industry has always been one of the more active industrial fields in China's technological transformation. In the 1990s, with the continuous introduction of high-tech printing technology and coding equipment, the Chinese printing and packaging industry as a whole became closer to the technological level of developed countries. It is said that the energy of the particles in the plasma is generally about a few to tens of electron volts, which is greater than the bond energy of polymer materials, and can completely break the chemical bonds of organic macromolecules to form new bonds; the plasma equipment of the inkjet printer is effective One of the surface treatment processes for cleaning, activating and coating. It can be used to treat various materials, including plastics, films, flexible packaging, coated paper, thermal paper, metal and paper. After the surface treatment of the inkjet printer with plasma equipment, the UV coating or plastic sheet is subjected to certain physical and chemical modification to improve the surface adhesion, so that it can be bonded as easily as ordinary paper, and the inkjet printer industry is developing Steadily move forward in the pace. The use of conventional water-based cold glue can make the laminated or glazing cardboard be reliably bonded on the folder gluer. There is no need for partial laminating, partial glazing, surface grinding and cutting, and no longer need because Replace different special glues for different cardboards. The plasma equipment of the inkjet printer has a small but very uniform surface treatment depth of the material; there is no paper dust droplets, which is environmental protection; the plasma nozzle has a certain distance from the material, and only the low temperature plasma is sprayed through the nozzle to apply glue. It can work continuously, and the product quality is stable; it does not need to consume other fuel during the work, and it can be operated by only connecting to the ordinary power supply, which greatly reduces the packaging and printing costs, but the plasma equipment will produce ozone during the work process, and make good deodorization facilities.
