Paper packaging printing technology presents new features

Modern science and technology are applied to the field of packaging and printing, so that many packaging and printing processes are simplified and more scientific and rational. For example, in the past, the molding process of plastic packaging, such as extrusion, hot pressing, stamping, etc., has gradually been used in the formation of cardboard packaging, so that paper packaging cannot be used for products that cannot be packaged in the past. As a result, paper packaging printing technology has also changed. Looking at the development of paper packaging printing technology has the following new features: First, the development of single-layer materials to multi-layer materials; Second, offset, gravure, flexo, screen printing and other printing methods coexist, in which flexographic printing will increase The third is the development of sheet-fed paper to roll paper and stand-alone-to-line production, and supply of complete sets of equipment; Fourth, 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 fifth is increasingly subject to increasingly stringent environmental and health standards.

At the same time, it can also be seen that the packaging and printing treatment process is more scientific and applicable, and the packaging performance and effects have undergone significant changes. For example, in the past, wax coating and film lamination in the packaging surface treatment have been replaced by surface gluing (spray-bonding), and anti-counterfeit packaging production technology has shifted from partial printing or production to integral large-area printing and production. . The prepress and postpress printing of the current packaging and printing, the use of computer technology, new equipment to complete the upgrading of production factors, and post-press processing technology innovations have enabled the post-press processing industry to form a new industrial structure and product structure adjustment connotation and commercial behavior in the packaging and printing industry.

The 11 new technology products announced by the Printing Technology Association of America in the future will have a real impact on the packaging and printing industry: these 11 new technologies include: the first PDF-based high-end prepress production system; dedicated to flexographic Network technology; Bora cutting system with CIP3 workflow; Offset transfer machine; The first process system that successfully uses laser technology to engrave gravure cylinders; Professional digital photographic technology; Drying new technology (on-line formation at one time); Sennheiser brand new technology; software package (prepress system); scanning software system; printing system for on-demand printing market.

We must also solve ten key technical problems in the development of the paper packaging industry: 1. Research on key technologies and equipment for the recycling of paper packaging materials and containers; 2. Systematization and intelligentization of paper packaging design; 3. Paper packaging Research and development of containers; 4. Research and development of key technologies and major equipment for manufacturing paper packaging materials; 5. Integration and application research of paper packaging technologies; 6. Development and research of paper product packaging machinery; System integration research; 8. Research on home appliance packaging technology and transport packaging; 9. Research on key technologies and new equipment for packaging and decoration printing; 10. Research on military product packaging technology.

In addition, the key development trend of paper products packaging is low-weight, high-strength, lightweight high-grade paper packaging, to achieve standardization, serialization, multi-species, multi-substrate, multi-purpose goals. In the next 10 years, paper media printing will have a huge development along with broadband. CIP digital printing presses are also making traditional processes more rational and labor-saving.
