Abstract
A polyester film which shows, upon preparation of a film-laminated metal plate by laminating the film of one side of the metal plate made of a tin free steel, a coefficient of kinetic friction at 80 degrees Celsius at the surface thereof of not more than 0.45 and an ethylene terephthalate cyclic trimer content of not more than 0.7 wt %, and a dimensional change of not more than 2.0% after a heat treatment at 210 degrees Celsius for 2 minutes of the film laminated metal plate. This polyester film is superior in heat resistance, barrier property and corrosion resistance, and is preferably used as a material forming a metal container for food.
