Stretched blow molding articles are prepared by using an aliphatic polyester composition having a melting point of at least 70.degree. C. including: 97.5 to 75 parts by weight of an aliphatic polyester copolymer (A) having a Mn of at least 50,000 which is obtained by reacting 100 parts by weight of a polyester diol (a) with 0.1 to 5 parts by weight of diisocyanate, wherein the polyester diol (a) is obtained by conducting a polycondensation of 1 mol of an acid component consisting of 70 to 90 mol % of succinic acid and 10 to 30 mol % of adipic acid, with 1 to 1.1 mol of glycol; and 2.5 to 25 parts by weight of potybutylene succinate (B) with a linear structure, (C) with a branched long chain structure, or (D) with a branched longer chain structure, which have an Mn of at least 50,000 and are composed from some of succinic acid, 1,4-butanediol, polyfunctional comonomer and di- or poly-functional coupling agents.
