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.
