a) Melting PBAT and blending with PLA or PPC
The molten PBAT material with a temperature of 240 ℃ is pumped into a twin-screw extruder through a melt pump, and PLA or PPC pellets and chain extenders are added to the extruder through weight loss feeding. This is direct blending, which can save 40% of energy and provide better dispersibility compared to blending PBAT particles with PLA or PPC
