<p>The application of modern technology in the field of packaging printing has simplified many packaging printing processes and made them more scientific and reasonable. For example, in the past, plastic packaging, such as extrusion, hot pressing, stamping, and other molding processes have gradually been applied to the molding of cardboard packaging, so that products that could not be packed with paper in the past also used paper packaging. As a result, paper packaging printing technology has also changed. Looking at the development of paper packaging printing technology, there are the following new features: First, the development of single-layer materials to multi-layer materials; second, coexistence of multiple printing methods such as offset printing, gravure printing, flexo printing, and screen printing, among which flexographic printing will grow The fastest; the third is the development of sheet paper to web and the single machine to online production to achieve the supply of complete sets of equipment; the fourth is the comprehensive application of various related new technologies (such as computer design, digital technology, laser processing technology and new materials, etc. ) Continuously optimize the entire production system; Fifth, it is increasingly restricted by increasingly stringent environmental protection and hygiene standards</p>
