Abstract

The present invention discloses a biodegradable polyester composition, wherein based on a total weight of the biodegradable polyester composition, a weight content of styrene is 0.1 ppm-30 ppm. When the weight content of styrene which is added into a chosen formula of the biodegradable polyester composition based on the total weight of the biodegradable polyester composition is controlled as 0.1 ppm-30 ppm, the present invention may guarantee the biodegradable polyester composition with excellent transmittance and haze effect, and meanwhile may guarantee the biodegradable polyester composition with suitable UV resistance function, without reducing a degradation rate of the biodegradable polyester composition.
