Effect of polyvinyl alcohol on tensile properties and morphology of sago starch plastic films
In this paper, sago starch films were prepared by blending process and casting method. The tensile properties and morphology of this film were studied. From the results, polyvinyl alcohol (PVA) was found to have the best tensile strength at about 10.0 MPa, and its elongation at break was 77 %. Additionally, 3.0 g of PVA showed the best tensile properties compared to the other amount. From scanning electron microscope (SEM), smoother and flatter surface morphology of the sago starch films with the presence of 1.0 and 3.0 g of PVA content were observed.
