The choice of tape

Why does tape stick to things? Of course, it's because it's coated with a layer of adhesive on its surface! The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because their own molecules form bonds with the molecules of the objects to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive, according to different brands, different types, there are various polymers.

The tape is based on the BOPP film, after high-voltage corona, the surface is roughened, coated with glue, and then divided into small rolls, which is the tape we use every day. Tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component is tincture. Tincture is a polymer active substance, and the temperature has a certain influence on the molecular activity. The tincture content of the glue directly affects the use of the tape. The initial adhesion of normal sealing tape is between ≥ 13 (steel ball size), and the thickness of this tape glue is generally 22 microns. is a standard thickness.
