LAMINATED POLYPHENYLENE SULFIDE FILM AND MANUFACTURE THEREOF

摘要

PURPOSE:To impart heat sealing properties to a biaxially oriented poly-p- phenylene sulfide film and improve its tearing strength while keeping its mechanical characteristics and heat resistance. CONSTITUTION:A laminated polyphenylene sulfide film wherein a surface layer consisting of a polyphenylene sulfide film of specifically copolymerized elements is laminated on at least one side of a center layer consisting of biaxially oriented poly-p-phenylene sulfide.
