(57) Abstract: A stretched aliphatic polyester film having excellent flexibility and heat resistance, in which a plasticizer does not bleed, an aliphatic polyester composition as a raw material of the stretched film, and use of the stretched film Provide a package. SOLUTION: With respect to 100 parts by weight of an aliphatic polyester, a general formula: R 1 OCH 2 CH (OR 2 ) CH 2 OR 3 (wherein at least one of R 1 , R 2 and R 3 has 6 carbon atoms) ~ (A) a compound represented by the formula (A), which is a hydrogen atom or an acetyl group: Aliphatic polyester composition containing 10 to 60 parts by weight of at least one compound selected from compound (B) which is a reaction product of a condensate of 10 to 10 molecules with a carboxylic acid having 6 to 18 carbon atoms, Crystallinity of molded product is 20-60% The stretched aliphatic polyester film, and a package using the stretched film. |
