PE  self-sealing bag blowing machine production process and production  principle: the dry polyethylene particles added to the next hopper, by  the weight of the particles themselves from the hopper into the screw,  when the pellets and threaded oblique contact, the rotation of the  oblique face The plastic produces a thrust perpendicular to the oblique facet and moves the plastic particles forward.

In  the process of moving, due to the friction between the plastic and the  screw, the friction between the plastic and the barrel, and the  collision between the particles, and gradually melt due to the external  heating of the cartridge. The  molten plastic is filtered through the nose to remove impurities from  the die die, cooled by the wind ring, inflated by the word plate,  traction roller, take the finished film rolled into a tube. Uses  and Features The device uses dual frequency control, you can save  energy, the unit extruder, barrel, screw are made of high quality alloy  steel, tight nitriding and precision machining, with the best hardness  and corrosion resistance , Specially designed screw production is high, good plastic. (HDPE) linear low density polyethylene (LLDPE) and other plastic film,  widely used in food, clothing, garbage bags, vest bags and other  civilian and industrial packaging.

Low-pressure  polyethylene (HDPE) and linear low-density polyethylene (JJDPE) is the  international market in recent years, a large number of new varieties of  polyethylene. Because  it has excellent impact strength, puncture resistance, resistance to  environmental stress cracking, low temperature performance, in  particular, can be made microfilm (1.5 silk thickness of the film can be  enough to reach the thickness of 3 thick high-pressure polyethylene  film) The The use of low cost, so a lot for blown film. Can  be blown low pressure, high pressure, linear low density three  polyethylene film, not only to adapt to their new material blown film,  but also for their recycled plastic blown film, stable performance,  reliable quality, the blown film machine with a special structure of the  spiral Rod  extruder, advanced screw die, adjust the flexible cooling air ring, a  reasonable aperture-shaped foam structure, so as to ensure that the  three kinds of polyethylene and different proportions of mixed plastic  uniform.
