PROBLEM TO BE SOLVED: To prepare a polyester film which is used, e.g. for the prevention of corrosion of a metal container used for refreshing drinks, beer, canned foods, on the like; a film-laminated metal sheet prepared by laminating the film to a metal sheet; and a metal container having a containing section formed from the film-laminated metal sheet. SOLUTION: The polyester film, formed from a polyester resin, has a coefficient of dynamic friction at 80 deg.C against a metal sheet surface of 0.45 or lower and a content of a cyclic ethylene terephthalate trimer of 0.7 wt.% or lower. When the film is eluted with water at 125 deg.C for 30 min, the concentrations of the cyclic ethylene terephthalate trimer, antimony, and germanium in the resultant eluate satisfy formula 1: CT<=700 and formula 2: A+B<=100 [wherein CT is the elusion concentration (μg/kg) of the cyclic ethylene terephthalate trimer; A is that (μg/kg) of anitimony; and B is that (μg/kg) of germanium]. |
