The nanometer calcium carbonate (nano-CaCO 3 ) filled Poly-dl-lactide (PDLLA) bio-composites were prepared with a twin-screw extruder. The melt volume flow rates (MVRs) and melt densities of the composites were measured by means of a melt flow rate instrument under experimental conditions at a temperature range from 180 to 230°C and a load range varying from 2.16 to 10kg. The result showed...
