The history of tape

Applications were filed in the United Kingdom and the United States on May 30, 1928. Drew developed a very light, one-press-fitting adhesive, which was not sticky enough in one attempt, so Drew was told: "Get this thing back." Go to your Scottish bosses and ask them to put more glue!" ("Scotland" means "mean" but during the Great Depression, people found hundreds of uses for this tape, from repairing clothes to protecting bumps. Broken eggs are very useful.

Why can tape stick things? Of course it is because it is coated with a layer of adhesive! Adhesives come 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, which 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.

Heat shrinkable film

Adhesive tape is based on the original BOPP film after 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.

Adhesive tapes can be divided into high temperature tapes, double-sided tapes, insulating tapes, special tapes-pressure sensitive tapes, die-cut tapes according to their functions. Different functions are suitable for different industry needs.

Quality judgment of sealing tape

The quality of sealing tape is simply judged as follows:

1. Look at the total thickness of the tape;

2. Look at the tension of the tape;

3. Look at the glue (that is, stickiness) of the tape;

4. Look at the peel strength of the tape. Another way is to take a piece of tape and seal it on the box to see if it is easy to warp, whether it is easy to pull off, and whether the surface of the carton can be damaged after tearing.
