This set of three-layer co extrusion film blowing unit is equipped with upper traction rotating system, internal cooling system, deviation correction system, hydraulic screen changing system, etc.

What are the advantages of the upper traction rotary system

1. Replace the rotary die head to solve the problems of long runner, difficult melt sealing, easy material leakage, and difficult maintenance of the rotary die head of the film blowing machine;

2. The defects such as "reducer" and "ruffle" caused by rotating die head are avoided;

3. At the same time, it will help to improve the output of shrink film blowers;

About IBC (ultrasonic closed-loop control) system:

It is composed of gas exchange device, internal cooling air ring, inlet and exhaust fans, signal detection, control circuit, etc. This system has the characteristics of fast cooling the film bubble, timely removing the heat, water molecular substances and waste gas in the film bubble, supplementing new cold air, reducing the internal temperature of the film bubble, and improving the production of PE film blowers and the mechanical properties of the film.
