On May 30, 1928, in the United Kingdom and the United States, Drew developed a very light, pressure-sensitive adhesive, which was later invented and improved.
The adhesive tape is a tape that we use every day after applying high pressure corona on the basis of the original film of BOPP to roughen one surface and apply glue after being divided into small rolls. Adhesive tape glue is acrylic glue, also called pressure-sensitive adhesive, the main ingredient is blusher. Rouge is a kind of macromolecular active substance, and the temperature has a certain influence on molecular activities. The blush content of the glue directly affects the use of the tape. The initial adhesion of normal sealing tape is between ≥13 (steel ball number). The thickness of this tape glue is generally 22 microns, which is the thickness that meets the standard.
For the color tape is for the convenience of marking and shielding purposes, generally more yellow and yellow earth. The color of the colored tape is the color of the glue.
Squeeze the adhesive tape tightly and then quickly pull it apart to remove the adhesive on one side and you can see the purity and transparency of the original film.
