The global economy and industrial system is rising with the packaging revolution as the guide of "zero packaging", "simplified packaging", "green packaging" ideas, and put into practice, green goods and green packaging has become a hot spot in the packaging industry. Green packaging is a kind of high-tech packaging, starting from raw materials, packaging design, manufacturing and product recycling, every link should be source saving, efficient and harmless. Ecological packaging materials have been widely concerned in the world, and its research should be considered from the whole process of development, design, production, use and waste.
The future of packaging will be green packaging, paper packaging and paper packaging containers as a member of green packaging, how will it develop?
The development of paper packaging and printing technology will have the following new characteristics: single-layer materials to multi-layer materials; Offset printing, gravure printing, flexographic printing, screen printing and other printing methods coexist and flexographic printing will grow the fastest; Sheet paper to web, single machine to on-line production direction; The integrated application of various related new technologies (such as computer design, digital technology, laser processing technology and new materials, etc.) continuously optimizes the whole production system.
The development trend of paper packaging containers is: a molded paper container will gradually replace the present die cutting combination of paper containers; Deep coating technology gradually replaces the past wax; Composite technology has become an important technique in paper container development. 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 low weight, high strengthening, lightweight high-grade paper packaging, to achieve standardization, serialization, multi-variety, multi-substrate, multi-purpose goals.
So paper packaging will be the product of the current market demand.
