Abstract: PURPOSE:To obtain a laminate combining each characteristic of heat resistance, chemical resistance, flame-retardant properties, shock resistance, resistance to moist heat, workability, etc., in a balanced manner by laminating a biaxially oriented polyphenylene sulfide layer on at least one side of a non-oriented polyphenylene sulfide layer without through adhesives. CONSTITUTION:A biaxially oriented polyphenylene sulfide layer is laminated on at least one side of a non-oriented polyphenylene sulfide layer without through adhesives. A film or a sheet or the like in 1mm or less manufactured by melting and molding a composition containing not less than 60wt.% polyphenylene sulfide is used as a non-oriented sheet. A film obtained by melting and molding a resin composition including not less than 90wt.% polyphenylene sulfide, forming the resin composition to a sheet shape and biaxially orienting and thermally treating the sheet-like resin composition is employed as a biaxially oriented polyphenylene sulfide film. Both the sheet and the film are thermocompression-bonded at a high temperature and high pressure or PPS is melt-extruded and laminated directly onto the biaxially oriented film as a laminating method. The former method is executed by a roll press, a hot plate pres, etc., under the conditions of a temperature of 180-270 deg.C and a pressure of 1-20kg/cm .
