Film blowing machine process principle will dry polyethylene particles into the hopper, by the weight of the particles themselves from the hopper into the screw, when the particles and threads
After the oblique edges are in contact, the rotating oblique edges face the plastic and generate a thrust perpendicular to the oblique edges, pushing the plastic particles forward
At the same time, the friction between plastic and screw, plastic and barrel, as well as the collision and friction between particles, also gradually melt due to the external heating of the barrel.
The molten plastic is filtered by the machine head to remove impurities from the die head and the die mouth. It is cooled by the air ring, blown and expanded by the miter plate, drawn by the roller, and rolled to remove the finished film
Rolled into a cylinder
Self-sealing bag blowing machine is suitable for food, medicinal materials, documents, industrial packaging and export packaging of plastic products, fruits, food, clothing, textile and civil industrial products packaging, etc.
