The machine plasticates two identical or different raw substances by two extrudes and extrudes them into the complex machine head , then produces the coextruding molded complex film. By this way, it make possible to enhance the film's physical performance, rigidity, good insulation-proof and impenetrability. The machine entails advanced consecutive rotation machine head, ensures smooth and homogeneous products, meets the film's quality requirement during the subsequent working procedure of the packing machine or the printer, also is useable for manufacturing the complex bead sheen film, complex hydro-packing film, insulation film, multi-functional farming film, Etc, its application range is gradually widening to the target of plastic product development.
