PROBLEM TO BE SOLVED: To provide a laminating polyester film, which can cope with a severe forming work at the forming of a container or the like, further is excellent not only in an adhesion, especially in an adhesion after retorting but also in taste characteristics and is suitable for a metal can or the like manufactured through a forming work after its lamination to a base material. SOLUTION: This film is produced by arranging a B layer made of a polyester B, the major constituent component of which is an ethylene terephthalate containing 6-20 mol% of an ethylene 2,6-naphthalene dicarboxylate, on at least one side of an A layer made of a polyester A, the major constituent component of which is an ethylene terephthalate unit containing 0.1-5 mol% of an ethylene 2,6-naphthalene dicarboxylate unit. |
