Adhesive tape is composed of two parts: base material and adhesive, which connect two or more unconnected objects together by bonding. A layer of adhesive is coated on the surface. 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 things because their molecules and the molecules of the objects to be connected form bonds, which can firmly bond the molecules together. The composition of the adhesive varies according to different brands and types, and there are a variety of different polymers.
