probably due to the increased contact area of the starch granules compared to pellets of
TPS, allowing greater interaction between starch and PBAT. The method M1 resulted in films with better
mechanical properties when the concentration of PBAT was equal to 50%. With increasing concentration
of starch (>50%), blends can be prepared with the method M2 (starch granules)in a single extrusion phase
without loss of mechanical properties, which can result in lower production cost.
