Double-sided adhesive tape is a coiled adhesive tape made of paper, cloth and plastic film as the base material, and then evenly coated with elastic pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above base material. It is composed of three parts: base material, adhesive and isolation paper (film).

Tape can stick things because it has 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 that want to connect things. This bond can firmly bind molecules together.
