1. When the PE material is plasticized and extruded, this is the key to control the thickness of the electrostatic protective film. The uneven plasticization results in fine crystals on the surface of the PE electrostatic protective film, which affects the smoothness and thickness of the PE electrostatic protective film.
2. The PE material is blown out from the film head of the blow molding machine, and the standard size of the film head directly affects the thickness of the PE electrostatic protective film.
3. When traction through the traction roller, if the traction force is too large, the electrostatic protection film will simply expand and deform, resulting in a thinner thickness.
