Plastic film blowing machine except with reasonable flow design and the main parts are used processing equipment, ensure the channel high accuracy and good precision surface roughness, die provided strong interchangeability, small resistance, material flow, uniform temperature distribution, stable rotation of the body of the mould, sealing well. Machine screw and barrel, and nose channel for low temperature of EVA adhesive with special design and manufacture, the head according to the EVA to LDPE, HDPE, LLDPE, EVA, EAA and regeneration of mixed material in the head at different temperature in the die channels produced by pressure, accurate calculated their gap of flow. The production of plastic film blowing machine is the film, these films are widely used according to different materials and characteristics with multiple fields. Applicable to all kinds of high-grade packaging film, plastic bag film, protective film and so on. This film due to its good barrier properties, anti wet, anti frost, oxygen, fresh, oil, can be widely used in light and heavy packaging. Such as a variety of fresh fruits, meat dish, liquid beverage, pharmaceutical products, pickles, fresh milk etc..
