Why can tape stick things? Of course it is because it is coated with a layer of adhesive! 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 things because their own molecules and the molecules of the objects to be connected form bonds, which can firmly bond the molecules together. The composition of the adhesive, according to different brands, different types, there are a variety of different polymers.
Adhesive tape is based on BOPP high-voltage corona to make one surface rough, then coated with glue, and then divided into small rolls. This is the tape we use daily. Tape glue is acrylic glue, also called pressure-sensitive adhesive, the main component is tincture. Tincture is a kind of macromolecular active substance, and the temperature has a certain influence on molecular activity. The tincture content of the glue directly affects the use of the tape. The initial adhesive force of normal sealing tape is between No. 13 (steel ball number), and the thickness of this tape glue is generally 22 microns. It is the thickness that meets the standard.
Adhesive tape is too familiar to us. It is inseparable from life and office. Adhesive tape has the advantages of strong adhesion. It is widely used in related industries and daily life. This kind of tape is low in price and sticky. Better. Many consumers don’t know how to buy high-quality tapes. In fact, a good tape has to be subjected to high-voltage corona to make one surface rough, then coated with glue, and then divided into small rolls. A good tape is more flexible and has black impurities. There are fewer dots, and the finished product of transparent tape is generally pure white.
