A white laminated polyester film for metal lamination, comprising a layer (layer A) comprising a copolyester A and a layer (layer B) comprising a copolyester B, characterized in that (I) (i) the copolyester A is one containing 0 to 15 % by weight of rutile titanium oxide with an average particule diameter of 0.1 to 0.5 mu m and having a melting point of 210 to 245 DEG C, and (ii) the copolyester B is one containing 10 to 50 % by weight of rutile titanium oxide with an average particle diameter of 0.1 to 0.5 mu m and having a melting point of 210 to 245 DEG C and an intrinsic viscosity in the polymer portion of 0.46 to 0.66; (II) the following relationship holds between the intrinsic viscosity ( mu A) of the polymer portion in the copolyester A and the intrinsic viscosity ( mu B) of the polymer portion in the copolyester B: I mu A - mu BI , rho o: theoretical density of the whole laminated film, g/cm , rho i: density of polymer portion in each copolyester, g/cm , rho 1: density of rutile titanium oxide, g/cm , Xi: thickness of each layer, mu m, Wi: concentration of rutile titanium oxide in each copolyester, wt.%, and n: number of copolyester layers. This film is excellent in whitening power, formability, aroma retention, and heat resistance and is less likely to cause roll abrasion.
