摘要： The present invention provides a polycarbonate resin composition characterized by containing 73 to 94.5 mass % of a polycarbonate resin (A), 5 to 25 mass % of a phosphorus-based flame retardant (B), and 0.1 to 2 mass % of a fluoropolymer (C), and by having a flow value of 1×0.01 to 10×0.01 cm3/sec at 280° C. The present invention also provides a sheet and a film using the polycarbonate resin composition.

摘要： A thin sheet or film excellent in flame retardancy and light-blocking properties is provided. A battery pack case and others with high flame retardancy are each molded from this thin film. A thin sheet or film Including a specific phosphorus-containing flame retardant in a polycarbonate resin is excellent in thickness accuracy, flame retardancy and appearance. A thin sheet or film excellent in flame retardancy and also having a thickness of 0.01 to 0.25 mm was formed when controlling its thickness uniformly during sheet or film molding. Further, upon addition of carbon black, the resulting sheet or film was found to have good light-blocking properties and higher flame retardancy. Moreover, when used as a film packaging material for battery packs, the sheet or film of the present invention was found to be excellent in film strength and ultrasonic weldability.
