When modern science and technology are widely used in the field of packaging and printing, the packaging and printing process is simplified, fast, and more scientific and reasonable, making things that could not be done in the past become possible. 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.
The development of paper packaging printing technology has the following new features:
1. More and more stringent environmental and health standards are restricting.
2. The development of single-layer materials in the direction of multi-layer materials.
3. The development of sheet-fed paper to roll paper and stand-alone on-line production will enable the supply of complete sets of equipment.
4. 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.
5, offset, gravure, flexo, screen printing and other printing methods coexist, of which flexographic printing will grow fastest.
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.
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 For example, in the past, wax coating and film lamination in the packaging surface treatment have been replaced by surface gluing (spray-bonding), and anti-counterfeit packaging production technology has shifted from partial printing or production to integral large-area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.
