<p>[PROBLEMS] To provide a polyester resin composition which makes it possible, in melt-molding a resin material containing flakes of recycled PET bottles as the main component, to inhibit the whitening due to the crystallization of the resin and thereby retain transparency and attain high production efficiency. [MEANS FOR SOLVING PROBLEMS] A polyester resin composition obtained by melt-mixing two or more kinds of polyester resins, characterized in that when the sum total of all the acid components of the composition and that of all the glycol components thereof are each taken as 100 mole %, at least one of the specific dicarboxylic acids is contained as an acid component in an amount of 1 to 30 mole % and/or at least one of the specific glycols is contained as a glycol component in an amount of 1 to 30 mole % and that the germanium/antimony mass ratio of the polymerization catalyst contained in the composition is 10/90 to 99/1.</p> |
