Plastic Open Agent

PlasticOpen Agent

Principle
Beforefilm drawing process, put ultra-fine silica gelparticles in the plastic material to form a thin uneven layer on the filmsurface. This can effectively prevent low molecular weight components fromleaking or being entwined, thus making it easier to open plastic film.

Plastic open agent is non-toxic,tasteless, and features narrow particle size distribution, high purity andtransparency. It is widely used as anti-adhesive for plastic film such aspolyethylene, polypropylene, polyvinyl chloride, ethylene-propylene copolymer,polyester, etc.
