The effect of ZnO (zinc oxide) and glycerol concentrations on the mechanical properties of bioplastics made from Canna tuber (Canna edulis) starch

The problem of plastic waste in Indonesia is increasingly worrying due to its long degradation duration. Bioplastics made from starch are easily degradable nature and have a lower contribution environmental pollution. This study aimed determine the effect ZnO glycerol additions on thickness, tensile strength, elongation, Young’s Modulus, water absorption, biodegradation bioplastics. results indicate that adding has significant effects biodegradation. A high concentration was parallel an increase thickness bioplastic. low increases strength but decreases absorption. Glycerol at elongation. addition small amount positively affects
