Summary: | A biaxially stretched film which is characterized by containing a polyethylene naphthalate copolymer (A), and which is also characterized in that the average of hysteresis loss ratios after performing a tensile cycle test up to 5% tensile strain in the MD direction and in the TD direction is 47.0% or less. Consequently, the present invention is able to provide a biaxially stretched film that has excellent folding resistance and heat resistance. |
