Characterization and Parametric Study on Mechanical Properties Enhancement in Biodegradable Chitosan-Reinforced Starch-Based Bioplastic Film.

From the findings of varying glycerol loadings (40 wt.% to 80 wt.% at 10 wt.% increments, which corresponded to starch: glycerol ratio ( w / w ) of 20:8 to 20:16) on the mechanical properties of the synthesized bioplastic film, the results in Figure 3 show that tensile strength exhibited a decreasing trend, in which it dropped from 2.86 MPa to 0.24 MPa when the glycerol loading was increased from 40 wt.% to 80 wt.%, and in contrast the elasticity of the film showed an opposite trend ( p < 0.05).
