The main production principle of scotch tape

   Scotch tape is a product that we often use in our lives. Tape almost occupies the details of our lives. The humble adhesive tape plays a huge role. The main principle of its production is:
   1. Adhesive for tape: The material of the adhesive is natural rubber, which is used to increase the viscosity of the resin, plus an anti-aging agent that maintains the adhesion, a solvent that can decompose various solvents, and mix these ingredients to make an adhesive. . The adhesive was left in the container for 24 hours to remove air bubbles to make the texture uniform, and filtered to remove impurities through filter paper.
   2. OPP film of adhesive tape: BOPP film is a sheet made of high molecular polypropylene and then stretched. Apply a release agent on the back of the film to prevent the adhesion of the adhesive. If it is needed on the front side, apply an adhesive. It is known that one side of the scotch tape is adhesive and the other side is not adhesive. It is acrylic-styrene polymer copolymer, silicone, polyethylene wax and so on.
