Uses and Features  

1. The three-to-seven-layer co-extrusion die head is an advanced superposed die head in the world, wherein each layer of the die head can be independently heated and can hold heat-insulation medium to effectively insulate heat, so as to blow plastic films with larger temperature difference. The die head has advanced structure and uniformly-distributed runners which ensure the stability of fluid and uniform thickness of films. 2. The traction system adopts oscillating rotation in horizontal ±360° at a uniform speed, and meets the requirements of high precision and high-speed printing. IBC internal cooling system has advanced level in the world at present, and guarantees the stabile size of film bubbles by controlling and regulating air inlet and outlet quant¬¬¬¬ity while changing hot air inside the film bubbles, after four ultrasonic probes compute detected information. The transparency of the films is greatly improved while the productivity is increased, thereby increasing the additional values of the products. The full-automatic winding device realizes the full automatic control over winding, unwinding, cutting and unloading, and photovoltaic rectification system enables the winding to be more orderly, so as to improve the work benefits, lower the labor strength of workers, and reduce the rejection ratio generated in manual coil change. 3. The computer centralized control system. Three-to-seven-layer traction co-extrusion film blowing machine unit with rotary machine head is developed by our factory according to market demands, and absorbs the advanced levels of like products at home and abroad in structure design. The films are suitable for various middle and high-grade film packages, and can be widely applied to light and weight packaging for various fresh fruits, meat food, pickles, fresh milk, liquid beverage and medical supplies due to excellent barrier property, refreshment, moisture resistance, frost resistance, oxygen insulation and oil resistance.
