PROBLEM TO BE SOLVED: To provide a polyolefin resin laminated film having flame resistance, excellent in adhesion to encapsulation material such as EVA, and good in processability as a film and stiffness, and suitable for a solar cell back sheet.SOLUTION: The polyolefin resin laminated film includes at least one or more layers of an A layer and a B layer. The A layer contains; as a main component, random polypropylene (a) composed of a random copolymer of propylene and ethylene and/or other α-olefin; and a flame retardant. The B layer contains: as a main component, a homo-polypropylene (b) composed of a polypropylene single polymer (b); and the flame retardant, where the amount of the flame retardant in the A layer and the B layer are each in the range of 0.5 to 3 mass%. The polyolefin resin laminated film has a tensile elasticity of 800 MPa or more and flame resistance suit to UL94 HB. |
