ABSTRACT:
A laminate comprising a non-oriented polyphenylenesulfide film and a biaxially oriented polyphenylenesulfide film bonded on at least one surface of the non-oriented polyphenylenesulfide film without using an adhesive, and process for producing it. The delamination of the laminate can be prevented and the tear strength can be increased by suppressing the crystallization of the non-oriented polyphenylenesulfide film. Since an adhesive is not interposed and the main component of the layers of the laminate is polyphenylenesulfide, the laminate can have excellent heat resistance, chemical resistance, electrical insulating property, wet heat resistance and processability with a good balance.
