Anti-blocking Agent
Polymer films are prone to adhesion due to molecular chain forces, which affects production and use. By adding Bangkai silica as an anti-blocking agent to the masterbatch or during the melting process, a micron-scale concave-convex structure can be formed on the film surface, reducing intermolecular forces and significantly improving the film's release and ease of use.

FEATURES
  • Excellent anti-blocking performance:effectively reduce the adhesion between film layers to ensure smooth separation during processing and use

  • High dispersibility and compatibility:nano-scale particles are evenly distributed to avoid agglomeration and ensure the smoothness of the film surface

  • Excellent optical clarity:minimize light scattering, maintain high light transmittance of the substrate, and do not affect the aesthetics of the product

  • Food and drug grade safety certification:high-quality production line that meets food and drug standards, safe and reliable
