Abstract
An aliphatic polyester stretched film which has excellent flexibility and heat resistance and manifests no bleeding of a plasticizer, an aliphatic polyester composition which is a raw material of the stretched film, and a package using the stretched film. The film can be prepared from an aliphatic polyester composition comprising 10 to 60 parts by weight of at least one compound selected from (A) a compound represented by the general formula: R OCH CH(OR )CH OR (wherein, at least one of R , R and R represents an acyl group having 6 to 18 carbon atoms, and remaining groups represent a hydrogen atom or an acetyl group.) and (B) a compound which is a reaction product of a condensate of 1 to 10 glycerin units with a carboxylic acid having 6 to 18 carbon atoms, based on 100 parts by weight of an aliphatic polyester. The aliphatic polyester stretched film can have a crystallinity of 20 to 60% which is obtained by molding the composition, and the film can be formed into a package obtained.
