Three layer co extrusion film blowing machine

Dalian three layer coextrusion film blowing machine there are many ways to form, but generally speaking mainly divided into: coating, lamination and multi-layer coextrusion method; the foreign Co extrusion technology development very fast, especially in some developed countries, the multi-layer co extrusion composite membrane amount accounted for the film production volume of one-third of the above, and I between the Kuomintang and the Communist Party of China extrusion composite film of the annual output of only 5 million tons, the amount not to 10% of the total output of packaging film.

Once the tube is filled with agricultural products, the other end will also be sealed, resulting in anaerobic process, stable product quality and prevent mildew or insect reproduction. When you need to use the product, you can use a special machine to open the silo bag, out of the need of the local.

Blown film process: the hopper feed material extrusion, blown traction, the wind ring cooling, spica splint, traction and traction, film winding
