Product Detail
Product Description
The operation process of 3 Layer Co-extrusion LDPE Shrink Film Blowing Machine is to add dry polyethylene particles into the lower hopper, and enter the screw from the hopper by the weight of the particles themselves. Facing the plastic, a thrust perpendicular to the beveled surface is generated, and the plastic particles are pushed forward. During the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, and the collision friction between the particles, and also due to the external heating of the barrel and gradually dissolve. The molten plastic is filtered by the head of the film blowing machine to remove impurities and comes out of the die mouth, cooled by the wind ring, blown through the herringbone plate, traction roller, and coiled to roll the finished film into a cylinder.
