The preparation method of PP film includes blowing film and casting two kinds of processes, different processes need different antistatic agents. The blowing film process is to heat PP particles to a molten state, through extrusion molding made of film.
In the process of blowing film, the antistatic agent needs to have good dispersion and fluidity and can be evenly distributed in the PP particles to achieve a good antistatic effect. The casting process is the PP particles through the extruder extrusion film, and after stretching and directional processing to form a film.
In the process of casting, the antistatic agent needs to have good thermal stability and tensile properties and can maintain a stable antistatic effect under the action of high temperature and high tensile force.
