(57) [Abstract] [Problem] Excellent impact resistance at low temperature, good taste retention (flavor), and good adhesion to a metal plate. In addition, a biaxially stretched film for metal laminating, which is also excellent in film forming property (extrudability and stretchability), is provided. SOLUTION: A first layer (A) made of polyester having ethylene terephthalate as a main repeating unit, 20 to 60% by weight of polycarbonate and 40 to 100% of polyester. The polyester is formed of a composition of 80% by weight, and the polyester has ethylene terephthalate as a main repeating unit and has a terminal carboxyl group concentration of 10 equivalents / 10 6 g or more of 10 to 90% by weight and butylene terephthalate as a main repeating unit. Polyester having a terminal carboxyl group concentration of 20 equivalents / 10 6 g or less as a unit 10 A biaxially stretched film in which a second layer (B) consisting of 90% by weight is laminated. |
