Background

The adhesive tape is an article consisting of a base material and an adhesive, and two or more unconnected objects can be connected together through adhesion.

One side of the tape is coated with a layer of adhesive for adhering to an article. The adhesive can stick to the article because the molecules of the adhesive and the molecules connected with the article form bonds, and the bonds can firmly bond the molecules together. However, the adhesive has different polymers according to different brands and different types, which directly results in different adhesive properties of the adhesive tape.
