Open Masterbatch

In order to improve the opening property of the film and prevent its adhesion, the opening agent is usually added before the production of plastic film to improve the opening property. The early inorganic opening agent is to make the surface of the film uneven to reduce the negative pressure in the film to separate it. The late organic opening agent forms a layer of lubricating film on the surface of the film, reducing the friction coefficient of the film, so that they do not stick to each other. However, additives generally have different degrees of side effects, mainly for the organic opening agent has a large number of precipitates on the surface of the film, affecting the film printability, heat sealing property and color. If lubricants and organic dispersants are added to the formula, precipitates may be produced. The pollution to be packaged is very serious, especially in the food packaging, liquid packaging, pharmaceutical packaging and other fields.
