PROBLEM TO BE SOLVED: To provide a polyester packaging material which shows suppressed elution of antimony, is excellent in transparency, thermal stability and flavor retention property or in transparency, thermal stability, flavor retention property and gas-barrier property and hardly causes staining of a die at molding. SOLUTION: The polyester packaging material is obtained by molding a polyester composition comprising 100 pts.wt. polyester resin containing an antimony compound as a polycondensation catalyst and 0.01-30 pts.wt. partial aromatic polyamide. Here, the elution of antimony atom (Sb) from the polyester packaging material into water is≤1.0 ppb. COPYRIGHT: (C)2006,JPO&NCIPI
