Factors and principles of sticker printing

Self-adhesive labels have the advantages of no need to brush glue, no need to paste, no need to dip in water, no pollution, saving labeling time, etc., with a wide range of applications and convenient and fast. Self-adhesive is a material, also called self-adhesive label material, which is a composite material with paper, film or other special materials as the surface, adhesive coated on the back, and silicone-coated protective paper as the base paper. And after printing, die-cutting and other processing, it becomes a finished label.

At present, the global self-adhesive labels 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 printing self-adhesive labels. The main equipment is small and medium-sized unit printing units, mainly ink, using roll-to-roll printing, round-to-round die-cutting, with high production efficiency, advanced technology, and compliance with environmental protection requirements. Each half of the European market is letterpress and flexographic printing, similar to the American flexographic printing application. Letterpress printing uses UV inks, most of the equipment is stacked or satellite, and the material processing method is also roll printing. In the Asia-Pacific region, China's home-developed Asia-Pacific region, label printing is still relatively backward. Even for letterpress printing, only a few use UV ink equipment. Most label printing still uses resin inks. Roll-to-roll printing and sheet-fed printing coexist, due to the high proportion of manual marking, sheet-fed offset self-adhesive labels are widely used.

Labels are mainly used in products and industries such as daily chemicals, cosmetics, electronic appliances, medicine, daily necessities, food and beverage, supermarket retail and logistics. From the current market situation, the demand for daily chemicals, food and medical labels for products is particularly prominent. From the global label market, the current self-adhesive labels account for 40% of the market share, wet adhesive labels account for 42%, shrink labels and packaging films (packaging labels) account for 9% and 7%, respectively. Wet self-adhesive labels and self-adhesive labels occupy an absolute advantage in the global label market. With the continuous development of the label industry and consumer demand for packaging, in the future, the processing of wet self-adhesive labels will gradually reduce the number of self-adhesive labels and shrink sleeve labels will grow rapidly, and the printing label industry will gradually expand the demand for high-value-added adhesive material solutions.

With the entry of foreign label printing companies and products into China, the introduction of advanced equipment, technology and management experience, and the adhesive market has gradually been nurtured. At present, the country has been able to process various high-end labels, and some of them have been transferred to domestic processing outside of label printing. This is the main reason for the rapid development of domestic label printing.
