PREPARATIOM METHOD OF POLYMER FILM AND COEXTRUSION FILM

摘要

The present invention relates to a manufacturing method of a polymer film comprising a substrate film forming step of coextruding a first resin comprising a polyamide-based resin and a second comprising a copolymer comprising a polyamide-based segment and a poly-ether-based segment and to a coextrusion film comprising a substrate film containing a first resin layer comprising a polyamide-based resin and a second resin layer comprising a copolymer comprising a polyamide-based segment and a poly-ether-based segment.
