LAMINATED POLYPHENYLENE SULFIDE FILM AND PRODUCTION THEREOF.

摘要

A laminated polyphenylene sulfide film wherein the central layer comprises a biaxially oriented polyphenylene sulfide film and the surface layer comprises a phenylene sulfide copolymer containing a comonomer unit other than a p-phenylene sulfide unit in an amount of 3 to less than 50 mole %. The film has improved bondability, particularly heat sealability, without detriment to the heat resistance and mechanical properties inherent in a biaxially oriented polyphenylene sulfide film.
