The inherent tack of LLDPE & LDPE films are a detriment when used in films where self-adhesion is undesirable. Antiblocking agents function by roughening the surface of film which prevents the film from sticking to itself. The four major antiblocking agents are
  Diatomaceous earth
  Talc
  Calcium Carbonate
  Synthetic silicas
The performance of antiblocking agents depends on the particle size distribution, surface area and particle shape of the inorganic additive. The efficiencies and thus the loading in the end product of the antiblocking agents differ. Sidma Polymers offers various types of antiblocking masterbatch.
