Tape

History of Scotch Tape:

1928 Scotch Tape Richard Drew, St. Paul, Minnesota, USA

Applying in the United Kingdom and the United States on May 30, 1928, Drew developed a very light, one-press-fit adhesive. The initial attempt was not sticky enough, so Drew was told: "Take this thing. Take it back to your Scottish bosses and ask them to put more glue!" ("Scotland" means "stingy" but during the Great Depression, people found hundreds of uses for this tape, from repairing clothes to It is very useful to protect broken eggs.

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 molecules and the molecules of the objects to be connected form bonds. This bond can firmly bond the molecules together. The composition of the adhesive varies according to different brands and types, and there are various polymers.　　

Tape introduction: BOPP (biaxially oriented polypropylene) tape is an indispensable product in any enterprise, company, or personal life. The country does not have a complete standard for the tape industry. There is only one industry standard "QB/T 2422-1998 sealing Use BOPP pressure sensitive adhesive tape.

Tape is based on the original BOPP film, after being subjected to 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 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.

Tape can be divided into: high temperature tape, double-sided tape, insulating tape, special tape-pressure sensitive tape, die-cut tape according to its function. Different functions are suitable for different industry needs;

Use of tape

1. Sealing and securing various products

2. Provide protection during production
