The development of carton packaging printing technology will have the following new characteristics: single-layer materials are developing in the direction of multi-layer materials; offset printing, gravure printing, flexo printing, screen printing and other printing methods coexist and flexographic printing will grow the fastest; single-sheet paper To the development of web and stand-alone production; 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.
The development trend of paper packaging containers is: one-time molded paper container will gradually replace the current die-cut combined paper container; deep coating technology gradually replaces the past wax coating; composite technology has become an important skill in the development of paper containers; CAD and CAM systems Will greatly shorten the design and manufacturing cycle of paper packaging containers. In addition, paper product packaging focuses on the development of high-end paper packaging with low grammage, high reinforcement, and light weight to achieve the goals of standardization, serialization, multiple varieties, multiple substrates, and multiple uses.
