摘要：
An aliphatic polyester film which is synthesized from a glycol and an aliphatic polybasic acid having a melt viscosity of 2,000 - 100,000 poises at a temperature of 190°C and a shear rate of 100 sec⁻¹, and having a melting point of 70 - 200°C . The film is excellent in heat stability and mechanical strength as well as biodegradability when buried in the earth; and has low combustion heat than polyethylene and polypropyrene.
