PE film blowing machine is to heat and melt plastic particles and then blow them into a film. There are many kinds of film blowing machines, including PE, POF, PVC and so on. The new material is blown out with brand-new particles. The color is all weighed, clean and the bag is stretched well. Most of them use frequency converters. The way to save energy is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, but you actually only need 30Hz in production, which is enough for production. Those excess energy consumption will be wasted. The frequency converter is to change the power output of the motor to achieve the effect of energy saving. Blowing film is connected with bag making. Blowing finished film is only the first step. In the follow-up, sea demon takes making film bag as the terminal product. This is the selected machine. The machine should be selected according to the specification range of the terminal film bag. The film blowing machine is suitable for all kinds of high-grade film packaging. The film can be widely used in light and heavy packaging because of its good barrier, fresh preservation, moisture prevention, frost prevention, oxygen isolation and oil resistance. Such as all kinds of fresh fruits, meat food, pickles, fresh milk, liquid drinks, medical supplies, etc.
