PROBLEM TO BE SOLVED: To provide a polyester-based resin composition capable of obtaining a blow-molded article which has characteristics suitable for blow molding, is excellent in moldability at the time of blow molding, and has excellent impact resistance.SOLUTION: A polyester-based resin composition contains (A) a polyester-based resin which contains a terephthalic acid mainly as an acid component and ethylene glycol and 1,4-butanediol mainly as glycol components, has 80/20-30/70 mass ratio of the ethylene glycol to the 1,4-butanediol, and has a crystalline melting point of 160-205°C and an intrinsic viscosity of 0.5-1.4; and (B) a modified olefin copolymer having 2 to 20 carbon atoms. The polyester-based resin composition contains 0.2-25 pts.mass of the modified olefin copolymer (B) based on 100 pts.mass of the polyester-based resin (A).SELECTED DRAWING: None |
