The tape is made of high-pressure corona on the basis of the original film of BOPP, and after one surface is roughened, it is coated with glue and then divided into small rolls by tape. The tape glue is acrylate glue, also known as pressure sensitive glue, the main component is rouge. Rouge is a kind of polymer active substance, and the temperature has a certain influence on molecular activities. The rouge content of the glue directly affects the use of the tape. The initial adhesive force of the normal sealing tape is between ≥13 (steel ball number), and the thickness of the tape glue is generally 22 micrometers, which is a standard thickness.
For colored tapes, it is convenient for marking and shielding purposes, generally more beige and khaki. The color of the colored tape is the color of the glue.
The scotch tape is pinched and then pulled open quickly, and the rubber can be pulled off to reveal the purity and transparency of the original film.
