Features:
* 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.
