There is disclosed A polyester based resin composition (D) which comprises a polyamide resin (A) and a polyester resin (B), or a polyamide resin (A), a polyester resin (B) and a polyethylene terephthalate resin (C), characterized in that the polyester resin (B) is obtained by polycondensation of a dicarboxylic acid component containing 0.5 to 60 mol % of a dicarboxylic acid having a cyclic acetal skeleton and/or a diol component containing 0.5 to 60 mol% of a diol having a cyclic acetal skeleton, and that the blending proportions of the polyamide resin (A), the polyester resin (B) and the polyethylene terephthalate resin (C) are each in the range of 1 to 99% by weight, 1 to 99% by weight and 0 to 98% by weight, respectively on the basis of total sum weight of the components (A), (B) and (C). There is further disclosed a molded product (film, sheet, thin wall hollow container, etc.). The above polyester based resin composition and a product molded therefrom are each excellent in transparency color tone, gas barrier properties, pinhole resistance and mechanical performance. |
