PROBLEM TO BE SOLVED: To obtain a biaxially drawn film of a biodegradable polylactic acid with good appearance and with excellent cutting properties by hand, i.e., easily openable properties. SOLUTION: A polylactic acid biaxially drawn film comprising a polylactic acid polymer as a main ingredient and which has a tensile strength of 80-140 MPa and a tensile elongation of 30-100% measured by using an No. 2 test piece under a condition of JIS K 7127 at a tensile speed of 200 mm/min is provided. |
