1, adhesive tape balls are used as elastic balls to relieve pressure. Usually, the ball is glued together with adhesive tape to make it an elastic ball. But sometimes the adhesive force of the adhesive tape to the surface of the ball is too small, which leads to the ball not sticking. The adhesive tape consists of two parts: the base material and the adhesive, and two or more unconnected objects are connected together by bonding. Its surface is coated with an adhesive. The earliest adhesives came from animals and plants. In the19th century, rubber was the main component of adhesives.

2. The adhesive tape is the adhesive tape we use every day. On the basis of the original BOPP film, one side is roughened by high-voltage corona, coated with glue and divided into small rolls. Adhesive tape is acrylic adhesive, also called pressure sensitive adhesive, and its main component is tincture. Butyl ester is a kind of polymer active substance, and the temperature has a certain influence on the molecular activity. The butyl ester content of glue directly affects the use of adhesive tape. The initial adhesion of normal sealant tape is ≥ 13 (number of steel balls), and the thickness of this adhesive tape is generally 22 microns, which meets the standard thickness.
