The blowing film machine is mainly composed of extruder, die head, mold, cooling unit, bubble stabilizer, V-blade, pull-off roller, and winding unit, etc. The blowing film machine heats and melts plastic pellets into a film. There are various types of blowing film machines, including PE, POF, PVC, and so on. The film blown with brand new pellets is new material, with even color, clean, and good bag stretching.

During the blowing film process of the blowing film machine, there are three factors that directly affect the operation of the blowing film machine, which are:
Temperature
Blow film machine temperature is divided into machine chamber temperature and room temperature. Proper control of the temperature is crucial for better blowing film production and is the most critical stage in the entire process, directly affecting product quality to a great extent.
