Hydrated Amorphous Silica/Precipitated Silicon Dioxide/Silica Powder for opening agent
It is often difficult to separate the two layers of plastic film, and it is difficult to open the bag mouth when bagging, so white carbon black is a good opening agent. Due to a series of advantages of white carbon black products, it can be widely used in many fields.
Adding a small amount of opening agent (anti adhesion silicon dioxide) into the film formula will produce micro roughness on the film material surface, which can reduce or eliminate adhesion without damaging the balance of physical and optical properties of the film. Due to the existence of the bulge, the contact area between the plastic films is reduced, and the air is easy to enter between the films, effectively avoiding the formation of vacuum tightness between the films, thus preventing the occurrence of adhesion between the films.
