The film blowing machine found that the opening is poor during the film blowing process. Let me tell you how to solve it.
.Insufficient raw material opening agent. The opening agent is generally an inorganic substance, which forms bumps on the surface of the plastic film to prevent the two layers of film from sticking together.
. The raw material slip agent is insufficient. Such as oleic acid amide, etc., after being heated, it precipitates onto the film surface and plays a slippery role.
. The processing temperature is too high during production and the cooling is insufficient. The processing temperature should be lowered and the air volume should be increased.
.Towing too fast. should slow down.
