In 2511 in St. Paul, Minnesota, Richard Drew invented Scotch tape. Tape can be divided into: high temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, die-cutting tape according to its function. Different functions are suitable for different industry needs. The surface of the tape is coated with a layer of adhesive to make the tape stick to the object. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesive tape is composed of two parts: substrate and adhesive, which connect two or more disjoint objects together by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because their own molecules form bonds with the molecules of the object to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive, according to different brands, different types, there are various polymers. When peeling off the tape, because of the stickiness of the tape itself, it is easy to stick the surface items such as wall skins. At this time, after ironing with a steam iron, the stickiness of the tape will be reduced, as long as it is lightly torn. Peel off without damaging walls etc.
