In the 20 th century and the 30 th century, adhesive sticker materials are applied in the United states at first, and due to the fact that the requirement of special composite materials is continuously expanded, adhesive sticker printing is gradually developed into an independent printing field, and enterprises engaged in adhesive sticker label printing at home and abroad are more and more.
Major markets for stickers are the food and beverage, consumer goods for durability, medicine, home and personal care products, and industrial and retail label markets. In the future, with the increase of urban population, the demand of people on medical supplies will be increased continuously; meanwhile, the improvement of consumer consciousness and the development of internet economy become one of the most main driving forces for promoting the growth of the adhesive label market. In addition, along with the development of electronic commerce, the market capacity of the label adhesive is greatly increased, and the market demands the quantity of the self-adhesive label adhesive more and more.
Label adhesives, which are adhesives used in label materials to play an important role in adhesion, are generally produced using hot melt pressure sensitive adhesives. With the increasing market demand for self-adhesive labels, the existing production speed cannot meet the market demand, the production speed of label materials depends on the die cutting speed of the label materials, and the die cutting speed is closely related to the used label adhesive. The existing label adhesive has a die cutting speed of 20-50m/min in the die cutting process, and if the die cutting speed is increased, bad phenomena such as poor waste discharge, flashing, edge breakage and the like can occur, so that the development of the label adhesive capable of improving the die cutting speed has very important significance.
