The main component of self-adhesive is paper, film or special materials as fabric, and the back is coated with adhesive.

The earliest self-adhesive was produced by an American chemist. 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 things on, and they 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. By 1973, they applied this glue to the back of commonly used trademarks, and then glued a piece of paper coated with a trace amount of wax to 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.
