So far, almost all of plastic film have to use additives in order to solve thin-film in the manufacturing, processing, use the process of adhesion problems exist, A series of plastic openings agent (anti-viscosity),It can be used as film anti-adhesion agent of polythene, polypropylene, PVC, ethylene-propylene copolymer, polyester, etc. The mechanism is: to form uneven surface on plastic surface so as to prevent substance with low molecular weight from effusion and enwinding each other.

 

A series plastic anti-block agent specification 

 

Type                             Typical value	A-205

Working principle:

 

 Join the particles into plastic raw materials, in films and sheets formed on the surface of a large number of raised dots, open into two between the "bridging" phenomenon, while avoiding the two walls close together to form a "sticky knot "problem; the other hand, the air can be agents along the anti-block agent in the film / sheet material of the wall in order to offset the atmospheric pressure.  

 

 Applications:

 

     All kinds of PP, PE, PO films and sheets, the anti-block agent is a plastic bag / film the most commonly used additive materials industries, almost all of plastic bags / sheets, contain the agents, played so easy for anti-sticking film openings, sheet easy to separate results.
