Tape tape scotch tape history:
1928 scotch tape Richard drew, St. Paul, Minnesota, USA
May 30 1928 filed an application in Britain and the United States. Drew has developed a light adhesive that can be pressed immediately. The first attempt was not sticky enough, so Drew was told, "Take this thing back to your Scottish boss and ask them to apply more adhesive!" " ("Scotland" means "stingy" However, during the Great Depression, people found hundreds of uses of this tape, from mending clothes to protecting broken eggs.
Why can adhesive tape stick things? Of course, it is because its surface is coated with a layer of glue! The earliest adhesives came from animals and plants. In the19th century, rubber was the main component of adhesives. In modern times, various polymers are widely used. Adhesives can stick to things because they form bonds between their own molecules and the molecules of the connected objects, which can firmly stick the molecules together. The composition of adhesive, according to different brands and types, has a variety of polymers.
Introduction of adhesive tape: BOPP adhesive tape is an indispensable product for any enterprise, company and individual. There is no perfect standard in domestic tape industry, but only one industry standard, pressure-sensitive adhesive tape for BOPP sealing (QB/T 2422- 1998).
The adhesive tape is the adhesive tape that we use every day. On the basis of the original BOPP film, it is roughened by high-voltage corona, then coated with glue, and then divided into small rolls. Adhesive tape is acrylic adhesive, also called pressure sensitive adhesive, and its main component is tincture. Tincture is a kind of polymer active substance, and the temperature has a certain influence on the molecular activity. The tincture 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. This is the standard thickness.
Tape can be divided into high-temperature tape, double-sided adhesive tape, insulating tape, special tape-pressure-sensitive adhesive tape and die-cutting tape according to their functions, and different functions are suitable for different industry needs;
The basic test items of adhesive tape are as follows:
1 Appearance HG/T 2408- 1992
QB/T 2422 - 1998

[Edit this paragraph] The purpose of the adhesive tape
1. Seal and fix various products.
2. Provide protection in the production process
