Anti block additives and slip agents used in the production processes of plastic films to avoid the adhesion between the different overlapping layers and to improve extrusion process.
Opis
There are several anti-blocking additives on the market (organic and inorganic); the choice of the right product depends on the polymer used, the percentages that can be added, the specific needs of the manufacturer and the final application of the film.
The blocking force also acts on the resistance of two film layers to mutual sliding, i.e. increases the coefficient of friction (COF).
