A polyester film made from two kinds of polyester resinsnand having a specific DSC (and a specific glass transitionnpoint) is protrided, (i) which is superior in mechanicalnproperty, capable of thermocompresaion bonding with a metalnsheet, despite a high degree of crystallization of the film,nreduces quality change of plastic film laminated on the metalnsheet even if faced with variation of conditions ofnthermocompression bonding with the metal sheet, and which isncapable of thermocompression bonding even at a relatively lowntemperature, (ii) which is superior in formability, (iii) whichnis superior in flavoring property and impact resistance, andnwhich obliterates occurrence of whitening or delamination ofnthe film, or microcracks on the film, even if the film in thenmetal laminated sheet obtained by thermocompression bonding ofnthe film on the metal sheet or on the surface of a metal cannobtained by subjecting the metal laminated sheet to variousnform processings is crystallized, and (iv) which satisfiesnproductivity at an industrial scale. |
