Vest Bag Film Blown Machine Set

This vest bag film blowing unit has a significant energy-saving effect. During the extrusion process, high-quality alloy steel is selected as the barrel and screw materials. After nitriding and precision cutting, its hardness reaches the optimal level and has excellent corrosion resistance. In addition, we have also equipped the equipment with a special screw to ensure production efficiency and plasticization quality.
This vest bag film blowing unit is mainly suitable for blowing low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) plastic films. Its application range is extremely wide, including but not limited to food packaging, clothing packaging, luggage manufacturing, veterinary bags, etc.

* Convenient to transport and install,  simple to operate, powerful, reasonable structure and beautiful appearance. It is an innovative work with high cost performance.

* The produced vest bag has excellent impact strength, puncture resistance, environmental stress crack resistance and low temperature resistance.

* The specially designed screw, advanced double-layer spiral die and cold bubble device structure make the extruded film have excellent plasticizing effect, greatly increasing the tear strength and brightness of the film.

* The high-speed double-air venting ring with flexible regulation and uniform distribution of wind density and reasonable aperture-type foam structure ensures that the mixture of plastics in different proportions is evenly plasticized, and then the texture of the film is improved by automatic embossing.
