To eliminate deterioration of taste retentivity due to eluted component of a film while holding impact resistance at a low temperature and to improve adhesive properties to a metal plate by specifying extracted amount when a first layer of a biaxially oriented laminated film laminated with polyester is extracted by pure water.
The biaxially oriented laminated film is constituted by laminating a first layer A of polyester containing ethylene terephthalate as main repeating unit, and a second layer formed of composition containing 20 to 60wt.% of polycarbonate substantially represented by a formula as a repeating unit and 40 to 80wt.% of polyester. Extracted amount at the time of extracting the layer A of the film with pure water at 125°C for 30min is set to 2×10-2mg/cm2. In the formula, R1, R2 each indicates hydrogen atom, or 1-6C alkyl group, R3, R4 each indicates 1-5C alkyl group, phenol group or halogen atom, and m, n each indicates 0.1 or 2.
