PROBLEM TO BE SOLVED: To provide a biaxially oriented polylactic acid film for forming, capable of giving a formed product excellent in heat resistance, without being deteriorated in formability, and to provide a container given from the same. SOLUTION: This biaxially oriented polylactic acid film for forming consists mainly of a lactic acid-based resin, wherein the film has such a stress at 100% elongation and an elongation at break in the machine direction and the transverse direction of the film at 60°C as satisfying inequalities (1) and (2): (1) 70≤F100a+F100b≤110 [F100a is the stress (MPa) at 100% elongation in the machine direction of the film at 60°C; and F100b is the stress (MPa) at 100% elongation in the transverse direction of the film at 60°C]; and (2) 460≤La+Lb≤800 [La is the elongation (%) at break in the machine direction of the film at 60°C; and Lb is the elongation (%) at break in the transverse direction of the film at 60°C].
