Pockmarked paper. Glossy paper.

Self-adhesive label sticker printing is suitable for small machine printing. While talking about the self-adhesive label printing processing technology, the structure of the self-adhesive material is composed of three parts on the surface, namely the surface material. Adhesive and backing paper, but from the perspective of manufacturing process and quality assurance, the self-adhesive material consists of seven parts:

It is used to change the surface properties of the surface material. Such as improving the surface tension, changing the color, adding a protective layer, etc., to make it better accept the ink and easier to print, to prevent dirt, increase the adhesion of the ink and prevent the printed graphics from falling off. Surface coating is mainly used for non-absorbent materials, such as aluminum foil, aluminized paper and various film materials.

Extended information:

The earliest self-adhesive was produced by a chemist from 3M Company in the United States. It was in 1964. At that time, when he was studying various adhesive formulas, he formulated a new type of adhesive that was highly viscous but not easy to solidify. Use it to stick something on and it can be easily peeled off even after a long time. At that time, people thought that this kind of adhesive would not be very useful, so they did not pay attention to it.

In 1973, a new tape product development team of 3M Company applied this glue to the back of commonly used trademarks, and then stuck a piece of paper coated with a trace amount of wax on the glue. In this way, the world's first trademark paper was born. As a result, people gradually discovered the role of self-adhesives, and more and more people used self-adhesives.
