The Effect of Beeswax and Glycerol Addition on the Performance of Bioplastic Film Made of Konjac Glucomannan

In this study, bioplastics made of Konjac glucomannan have been successfully prepared via film casting method. The effects addition beeswax content (i.e. 0%, 0.5%, and 1%,), as well glycerol 1%, 1.5%) on the properties investigated. produced characterized for their tensile strength, percent elongation, swelling degree, biodegradability. results showed that most bioplastic samples weight loss about 95% after drying process finished film. concentrations also increased strength elongation bioplastics. highest value occurred at with a concentration 1.5% 1% Sample C3) approximately 3.5 MPa. Whereas, 23.29%. These values were higher or comparable to other from starch different raw materials reported by literatures. hand, decreased degree swelling. all in range 316.77 – 481%.
