摘要
A polyester film for metal sheet laminating. The film comprises a blend of (I) polybutylene terephthalate or a polyester comprising it as the main ingredient with (II) polyethylene terephthalte or a polyester comprising it as the main ingredient, the contents of the polyester (I) and the polyester (II) being 80 to 40 wt% and 20 to 60 wt%, respectively. This film has a melting point of 200 to 223 DEG C attributable to the polyester (I) and a melting point of 230 to 256 DEG C attributable to the polyester (II). The film as a whole has an intrinsic viscosity of 0.75 or higher.
