After blowing the film, cut out the vest bag.
Plastic particles are plasticized by the extruder and blown into films by the film blowing machine. Barrel films are cut into the desired shape by the vest bag making machine and the bottom is heat sealed.
The process is very simple, and there are corresponding machines.
The energy saving of the film blowing machine can be divided into two parts: one is the power part, and the other is the heating part.
Power part energy saving: most of them use frequency converters. The way to save energy is by saving the residual energy consumption of the motor. For example, the actual power of the motor is 50 Hz, but you only need 30 Hz in production. The excess energy consumption is wasted. The frequency converter is to change the power output of the motor to save energy.
