PROBLEM TO BE SOLVED: To provide a metal vessel having an excellent impact resistance, especially even after a treatment like baked paint, and a laminate film and a laminated metal board used for the vessel. SOLUTION: This is an amorphous non-oriented polyester film contg. a copolymer of polyethylene terephthalate. The polyester film to laminate a metal board is a copolymer having a group derived from naphthalene dicarboxylic acid and the components forming the film satisfy the following conditions,(1)-(3), and, moreover, the m.p. of the film is 200-250 deg.C. A laminated metal board is made by laminating the film over the metal board and a metal vessel is made using the laminated metal. (1) 3-12mol% of the dicarboxylic acid component is naphthalene dicarboxylic acid. (2) 75-97mol% of the dicarboxylic acid component is terephthalic acid. (3) Not less than 75mol% of a diol component is ethylene glycol. |
