PROBLEM TO BE SOLVED: To provide an aliphatic polyester film which is excellent in heat resistance, bending resistance, and transparency, and is useful as a bag for packaging, and to provide a laminated product. SOLUTION: The aliphatic polyester film is characterized in that it comprises 55-95 wt.% of an aliphatic polyester and 5-50 wt.% of a polyester elastomer having a melting point of 150-220°C and a glass transition temperature of not more than 0°C, and in that its crystalline melting peak lies in a range of 135-145°C.
