What are the new features of the development of carton packaging and printing technology?
Visit:271 Date:2018-06-12
Paper packaging has once again entered the eyes of people. The most primitive packaging, carton packaging has its green advantages. Metal, wood products and other packaging used once can rarely be reused, recycling costs are not as good as newspapers.  

    The global economy and industrial system is embarking on the concept of waterproof packaging, simplified packaging, and green packaging led by the packaging revolution and put into practice. Green goods and green packaging have become hot spots in the packaging industry. Green packaging is a high-tech form of packaging. From the beginning of raw materials, to the design and manufacture of packaging, and to the recycling of products, every link must be source-cut, efficient, and harmless. Ecological packaging materials have received extensive attention from the world, and their research needs to be considered from the process of development, design, production, use, and disposal.  

    The development of carton packaging and printing technology will have the following new features: the development of single-layer materials in the direction of multi-layer materials; multiple printing methods such as offset printing, gravure printing, flexo printing, screen printing, etc. will coexist and flexographic printing will grow fastest; sheet paper In the direction of web-to-web, single-machine-to-line production; comprehensive applications of various new technologies (such as computer design, digital technology, laser processing technology, and new materials) continue to optimize the entire production system.  

   The development trend of paper packaging containers is: once molded paper containers will gradually replace the current die-cut combination paper containers; deep plastic coating technology will gradually replace the past wax; composite technology has become an important technique for 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 low-weight, high-strength, lightweight, high-grade paper packaging that meets the goals of standardization, serialization, multi-species, multi-substrate, and multi-purpose.

   Small cartons and cartons often have various structural layouts. For example, there are layouts mainly based on field printing, as well as printed layouts in which textures, characters, lines, and solid patterns coexist; both gold and silver layouts in which spectrum colors cannot be displayed, and layouts in which spot colors and four primary colors coexist. If printing methods such as offset printing, embossing (or gravure printing, etc.) are used, the printed products have their own advantages in terms of process characteristics, and multi-processes can be combined to print packaging products such as paper boxes and cartons, which can improve the intrinsic quality of products.

   The offset printing process has good printing and reproduction effects, soft colors, clear dots, and rich printing layers. The printing of large-area layouts is not prone to the phenomenon of sticky products. The embossing and gravure printing process has the advantages of thick and full ink layers, bright colors and high gloss.
