The application of modern technology in the field of packaging and printing has simplified many packaging and printing processes and is more scientific and reasonable. For example, in the past, plastic packaging extrusion, hot pressing, stamping and other forming processes have been gradually used in the formation of cardboard packaging, so that products that could not be wrapped in paper in the past also used paper packaging.
The post-printing process of packaging is more scientific and practical, and the packaging performance and effects have changed significantly. For example, in the past, the wax coating and film coating processes in packaging surface treatment have been gradually replaced by surface glue (spray treatment), and there are also anti-counterfeiting packaging production processes. Shanghai Printing has changed from partial printing or production to overall large-area printing and production. Anti-counterfeiting. At present, the pre-press and post-press technology of packaging and printing uses computer technology, the new equipment completes the upgrade of production factors, and the innovation of post-press processing technology, so that the post-press processing field forms a new industrial structure of the packaging and printing industry, the connotation of product structure adjustment and business behavior.
The development of paper packaging printing technology will have the following new features: 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 fastest; single-sheet paper Develop towards web and stand-alone production; 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 containers will gradually replace the current die-cut combined paper containers; Shanghai printing deep coating technology gradually replaces the past wax coating; composite technology has become an important skill in the development of paper containers; CAD and The CAM system 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.
