PURPOSE:To prepare a polyester film which gives a metal-sheet laminate excel lent in formability into a can, heat resistance, impact strength, etc., by using a specific polyester film having a content of a specific free monomer of a speci fied value or lower. CONSTITUTION:This film comprises 99-60wt.% polyester having an m.p. of 210-245 deg.C and a glass transition point of 60 deg.C or higher and 1-40-wt.% polyester mainly comprising polybutylene terephthalate having an m.p. of 180-223 deg.C and contains 300ppm or lower at least one free monomer selected from among monomers represented by formulas [M-1] to [M-5]. |
