<p>The object of the present invention is to provide a polylactic acid stretched film having biodegradability and excelling in transparency and heat resistance. The main feature is characterized in that a polylactic acid stretched film is composed of a polylactic acid composition containing poly-L-lactic acid and poly-D-lactic acid in which a peak ratio (peak 1/peak 2) of a peak height (peak 1) of a maximum endothermic peak of endothermic peaks within a range of 150 to 200°C to a peak height (peak 2) of a maximum endothermic peak of endothermic peaks within a range of 205 to 240°C in DSC measurements is equal to or less than 0.2.</p> |
