The hottest self sealing bag blowing machine adopt

The self sealing bag film blowing machine adopts a unique structure

the production process and production principle of the self sealing bag film blowing machine: add dry polyethylene particles into the lower hopper, enter the screw from the hopper by the weight of the particles themselves, and when the particles contact with the threaded inclined edge, the rotating inclined edge generates a thrust perpendicular to the inclined edge face of the plastic, pushing the plastic particles forward

in the process of moving, due to the friction between plastic and screw, plastic and barrel, as well as the collision and friction between particles, and at the same time, due to the external heating of the barrel, it gradually melts. The molten plastic is filtered by the machine head to remove impurities, and comes out of the die mouth of the die head. It is cooled and expanded by the air ring, and then rolled into a drum by the herringbone plate, traction roller and coiling. Usage and characteristics the equipment adopts double frequency conversion speed regulation, which can save electric energy for you. The extruder, barrel and screw of this unit are made of high-quality alloy steel, tight nitriding treatment and precision processing, with the best hardness and corrosion resistance. The specially designed screw has high output and good plasticization. It is suitable for blowing plastic films such as low density polyethylene (HDPE), linear low density polyethylene (LLDPE), and is widely used in civil and industrial packaging such as food, clothing, garbage bags, vest bags, etc

low pressure polyethylene (HDPE) and linear low density polyethylene (jjdpe) are new polyethylene varieties with a total capacity of more than 170000 tons/year in the international market in recent years. Because it has many difficulties for China to realize the wide-ranging production of lithium alloys, it has excellent impact strength, puncture resistance, environmental stress cracking resistance, and low temperature resistance, especially it can make micro films (the development history of 1.5 bending tester, the strength of thin films with wire thickness is enough to be compared with that of high-pressure polyethylene films with 3 wire thickness). The use cost is low, so it is widely used for blowing film, so it does not occupy beat time. It can blow three kinds of polyethylene films: low pressure, high pressure and linear low density, which are not only suitable for their new material blowing, but also for their recycled plastic blowing. The film blowing machine has stable performance and reliable quality. The film blowing machine adopts a spiral rod extruder with special structure, advanced spiral die head, adjustable flexible cooling air ring, and reasonable aperture type bubble stabilizing structure, so as to ensure the uniform plasticization of the above three kinds of polyethylene and the mixture of different proportions
