| description | Provided is a polyester film, which is suitable for use in battery packages, particularly for use in deep drawn packages of lithium ion secondary batteries that comprise an electrolyte (in a solid state or in a liquid state), and which is also suitable for use in packages of pharmaceutical products that have various shapes. The polyester film is characterized in that the stresses at 5% elongation (F5 values) and the stresses at 10% elongation (F10 values) of the film in the longitudinal direction and in the transverse direction at 25°C respectively satisfy the following formulae (I) and (II). 1.5 ¥ F ¢ 10 MD / F ¢ 5 MD ¥ 1 1.5 ¥ F ¢ 10 TD / F ¢ 5 TD ¥ 1 |
