ABSTRACT:
The invention provides an aliphatic polyester resin composition that contains 100 parts by weight of an aliphatic polyester resin and from 10 to 60 parts by weight of at least one compound of a formula (1):wherein n indicates an integer of from 1 to 9, R1to R4each independently represent an alkyl group having from 1 to 17 carbon atoms, and when n is 2 or more, R3may differ in different units, a film formed of the composition, and packages with the film. The aliphatic polyester film of the invention keeps the degradability in the natural environment that is intrinsic to lactic acid-based polymer, and has good heat resistance, flexibility, transparency and adhesiveness, and, in addition, the plasticizer does not migrate to the surface of the film.
