The principle of using tape

Tape is composed of two parts: a substrate and an adhesive, which connects two or more disconnected objects together through bonding. It is coated with a layer of adhesive on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives; In modern times, various polymers are widely used. Adhesives can stick things because they form bonds between their own molecules and the molecules they want to connect to, which can firmly bond the molecules together. The composition of adhesives varies depending on the brand and type, and there are various polymers available.
