Summary:PROBLEM TO BE SOLVED: To provide a laminated polyester film for a metal laminate excellent in heat resistance, lamination properties, impact resistance and molding processability and suitable for a metal can, in particular an aluminum can. SOLUTION: The laminated polyester film is obtained by laminating a layer (B-layer) comprising polyester 3 with a melting point of 170-250°C on at least one surface of a polyester layer (A-layer) comprising a mixture of 70-20 wt.% of polyester with a melting point of 246-270°C and 30-80 wt.% of polyester with a melting point of 180-240°C. The thickness ratio of the B-layer in all of the layers is 1-10%. COPYRIGHT: (C)2004,JPO
