Double-sided sealing tape is a roll of adhesive tape made by evenly coating an elastomer-based or resin-based pressure-sensitive adhesive onto a paper, cloth, or plastic film substrate. It consists of three parts: the substrate, the adhesive, and a release liner (film).
Adhesive tape can stick things because it has an adhesive coating on its surface! The earliest adhesives came from animals and plants. In the 19th century, rubber was a major component of adhesives; while today, various polymers are widely used. Adhesives stick because their molecules form bonds with the molecules of the object being bonded, firmly binding the molecules together.
