PROBLEM TO BE SOLVED: To provide a film excellent in balance of impact strength, rigidity, and tear resistance. SOLUTION: The inflation film comprises an aliphatic polyester (A) and an ethylene-α-olefin copolymer (B), in which an activation energy (Ea) of the ethylene-α-olefin copolymer (B) is 20-44 kJ/mol; and, assuming that the total of the aliphatic polyester (A) and the ethylene-α-olefin copolymer (B) in the film is 100 wt.%, the aliphatic polyester (A) is 5-45 wt.% and the ethylene-α-olefin copolymer (B) is 55-95 wt.%.
