Summary:PROBLEM TO BE SOLVED: To provide excellent hot stick resistance, no dirt of a thermal head and excellent printability, by laminating a laminate film containing a mixture of a heat resistant resin and an oily substance as a constituting component on a biaxially oriented polyester film without any intermediary of an adhesive layer. SOLUTION: A polyester film is obtained by longitudinally and axially orienting the film before its crystal orientation is completed in the state that a laminate film is provided, and completing the orientation by heat treating to exhibit a biaxial orientation pattern by a wide angle X-ray diffraction. In the laminate film, a main constituting component is a mixture of a heat resistant resin and an oily substance of 70% or more contained in the film. The laminate film is laminated on at least one surface of the polyester film substantially without intermediary of an adhesive layer. Thus, excellent hot stick resistance, no dirt of a thermal head and excellent printability can be provided even in a high energy application area.
