摘要： A polyester film having a coefficient of dynamic friction between the film and a metal at 80.degree. C. of not more than 0.45, a polyester film composed of a polyester comprising an ethylene terephthalate unit in a proportion of 70% or more by mole, the polyester film comprising a cyclic ethylene terephthalate trimer in a proportion of 0.7% or less by weight, laminated metal sheets and metal containers manufactured from said laminated metal sheet. According to the present invention, the polyester film shows superior sliding property and superior scratch resistance during can production, as well as the elution of oligomer from the film can be suppressed, so that when the film is used for metal containers for food, the change in taste and smell of the food contained therein and degraded appearance of the surface of the film caused by the deposition of oligomer are avoided.
