<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a polyarylene sulfide laminated biaxially oriented film excellent in an interface adhesion property of a heat laminate laminated film and excellent in a handling property because of suppressing warpage of a heat laminate film. <P>SOLUTION: Thermocompression is carried out with a metal roll heated to 240°C or higher and a nip roll heated to 200°C or higher by using copolymerized polyarylene sulfide as an adhesion layer of a biaxially oriented polyarylene sulfide film. Immediately after the thermocompression, the biaxially oriented polyarylene sulfide laminated biaxially oriented film is obtained by making the film contact the metal roll for at least three seconds or more, removing the film from the metal roll, and laminating the film. <P>COPYRIGHT: (C)2012,JPO&INPIT |
