PURPOSE:To obtain excellent moldability, aroma-preservative property, and impact resistance by setting specified values for a fusion peak temperature face orientation coefficient, an average refraction factor, and a double refraction factor of a biaxially oriented film of a polyester resin A. CONSTITUTION:A metal sticking film is made of a biaxially oriented film consisting of a polyester resin A, where a fusion peak temperature of the film TA, a face orientation coefficient SA, an average refraction factor n, and a double refraction factor DELTAnA are made to be 200 deg.C<=TA<=240 deg.C 0.12<=SA<=0.14 1.585<=nA<=1.620 and DELTAnA<=12X10<-3>. It 15 desirable that the resin A is made of a polyester copolymer. For acid component, an aromatic dibasic acid, an aliphatic dicarboxylic acid, an alicyclic dicarboxylic acid or the like are suitable. For alcohol component, an aliphatic diol is suitable. The thickness of the polyester film is made to be 2-150mum. For metal plate, a tin plate, a tin-free steel, an aluminum and the like are exemplary. |
