А1:
Adhesive tapes generally have three materials: BOPP, PE, and PVC.
- BOPP: This material is used to make sealing tape and scotch tape. The scotch tape made of BOPP material has high strength, good transparency, good barrier performance to oxygen and nitrogen, and low temperature resistance. So deeply loved by users.
- PE: It uses different types and concentrations of catalysts, and changes the ratio of catalyst components and polymerization temperature to obtain PE with different properties. Different plastic additives can also be added according to user requirements to prepare pellets with different uses.
- PVC: It is a kind of general-purpose plastic, which has strong polarity and plasticization, and has good processing performance, and can produce products with various properties.
А2:
Usually the composition of the tape is composed of two parts.
