New trends and new features in the development of paper packaging and printing
When over-packaging became a street mouse, when everyone shouted, the paper packaging once again entered people's attention. The most original packaging, paper packaging has its green environmental advantages. Packaging of metal and wood products is rarely used once, and recycling costs are not as good as newspapers.
The global economy and industrial system are emerging with the concept of “zero packaging”, “simplified packaging” and “green packaging” led by the packaging revolution, and put into practice, green commodities and green packaging have become hot spots in the packaging industry. Green packaging is a high-tech packaging. From the beginning of raw materials, to the design and manufacture of packaging, to the recycling of products, every link must be resource-efficient, efficient and harmless. Ecological packaging materials have received wide attention in the world, and their research should be considered from the whole process of development, design, production, use, and disposal.
The future packaging will be green packaging, paper packaging and paper packaging containers as a member of the green packaging, in what form will it develop?
The development of paper packaging printing technology will have the following new features: single-layer materials will be developed in the direction of multi-layer materials; offset printing, gravure printing, flexo printing, screen printing and other printing methods will coexist and flexo printing will grow fastest; sheetfed Development of web-to-roll, stand-alone to on-line production; comprehensive application of various related new technologies (such as computer design, digital technology, laser processing technology and new materials) to continuously optimize the entire production system.
The development trend of paper packaging containers is that one-time molded paper containers will gradually replace the current die-cutting paper containers; deep plastic coating technology gradually replaces the past waxing; composite technology has become an important skill in the development of paper containers; CAD and CAM systems This will greatly shorten the design and manufacturing cycle of paper packaging containers. In addition, paper product packaging focuses on the development of high-grade paper packaging with low weight, high strength and light weight, achieving the goal of standardization, serialization, multi-variety, multi-substrate and multi-purpose.
CYW has been involved in the packaging and printing industry for more than 10 years and has a certain production scale. It has formed a complete and complete packaging industry system with complete categories of materials, products, machinery, packaging and printing, design and scientific research.
