Factors And Principles Of Self-adhesive Printing

The label has the advantages of no glue, no paste, no dip, no pollution, simultaneous interpreting and saving time. It has wide application range and is convenient and quick. Self adhesive is a kind of material, also known as self-adhesive label material. It is a composite material with paper, film or other special materials as the fabric, adhesive coated on the back and silicon coated protective paper as the base paper. And after printing, die-cutting and other processing, it becomes a finished product label.

At present, the global self-adhesive label can be divided into three camps according to different printing methods. North America is the leading technology of flexographic printing as a typical representative of self-adhesive label printing. The main equipment is a small and medium-sized unit type printing unit, which mainly uses ink. It uses roll to roll printing, circular pressing and circular die cutting. It has high production efficiency, advanced technology and meets the requirements of environmental protection. Relief printing and flexographic printing in every half of the market in Europe are similar to flexographic printing in the United States. All relief printing uses UV ink. Most equipment is used as stacking or satellite, and the material processing method is also rolling printing. In the Asia Pacific region of embossing and family development in China, label printing is still relatively backward. Even for letterpress printing, only a few use UV ink equipment. Most label printing still uses resin ink, and roll to roll printing and sheet fed printing coexist; Due to the high proportion of manual marking, sheet materials are widely used in sheet fed offset self-adhesive labels. 

Labels are mainly used in products and industries such as daily chemical industry, cosmetics, electronics and appliances, medicine, daily necessities, food and beverage, supermarket retail and logistics. From the current market situation, the demand for medical labels of daily chemicals, food and products is particularly prominent. From the global label market, the current self-adhesive label accounts for 40% of the market share, wet adhesive label accounts for 42%, shrink label and packaging film (packaging label) account for 9% and 7%, and the global label market of wet self-adhesive label and self-adhesive label occupies an absolute advantage. With the continuous development of the label industry and consumers' demand for packaging, the processing of wet self-adhesive labels will be gradually reduced in the future, the number of self-adhesive labels and shrink sleeve labels will increase rapidly, and the printing label industry will gradually expand the demand for high value-added and add bonding material solutions. 

With the entry of foreign label printing enterprises and products into China, the adhesive market is gradually bred after the introduction of advanced equipment, technology and management experience. At present, China has been able to process all kinds of high-grade labels, and some of them have been transferred to domestic processing in addition to label printing. This is mainly due to the rapid development of domestic label printing.
