Methods of making biodegradable films having enhanced ductility and breathability |
摘要 |
The present invention is directed to methods of making biodegradable films and biodegradable precursor films having enhanced breathability and ductility. The method includes blending a water soluble polymer and a biodegradable polymer to form a blended polymer mixture. The biodegradable polymer is preferably a biodegradable aliphatic polyester, and the water-soluble polymer is preferably polyethylene oxide and/or polyethylene glycol. The blended polymer mixture is formed into a precursor film. The precursor film is further processed to form a breathable biodegradable film.
