Title:
BIODEGRADABLE POLYESTER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2017/152773
Kind Code:
A1
Abstract:
The present invention discloses a biodegradable polyester composition, wherein, tetrahydrofuran is contained in a weihgt content of 3ppm-200ppm,cyclopentanone is contained in a weight content of 0.5ppm-85ppm, based on the total weight of the biodegradable polyester composition. By adding tetrahydrofuran and cyclopentanone in the composition and controling the contents thereof in certain ranges,the present invention may significantly improve the poor printing phenomenon of a biodegradable polyester composition during printing, and prevent not only ink being separated from a film, but also too much ink being adhered to the film, thereby allowing the film to exhibit an excellent printing performance. In addition, the present invention may improves the lubrication degree of the film of the biodegradable polyester composition during blow molding, and ensure the stability of the bubbles and the continuity of the film blowing at a film blowing speed of 176Kg/h, a film thickness
range of <0.2 μm and a film thickness relative deviation of <1％.
