    摘要： The present invention discloses a biodegradable polyester composition, wherein based on a total weight of the biodegradable polyester composition, a weight content of a cyclic ester compound having a structure shown as formula (I) is 100ppm-950ppm;

    and based on the total weight of the biodegradable polyester composition, a weight content of tetrahydrofuran is 3ppm-200ppm. In the present invention, by adding the cyclic ester compound and tetrahydrofuran into the composition and controlling the content of the cyclic ester compound and the content of tetrahydrofuran in a certain range in the composition, an anti-thermal oxidative aging property of the biodegradable polyester composition can be greatly improved. Besides, after being digested with 95% ethanol at 40°C for 240 hours, a film prepared by blow molding or a part prepared by injection molding has little precipitate separating out of the surface and has an excellent surface appearance property. Also, poor printing of the biodegradable polyester composition during printing process can be greatly improved and the film shows excellent printing performance.
