Abstract This paper focused on green-production of bioplastic films and characterization of starch based bioplastics. The starch powders were extracted from fresh corn and cassava by cold extraction method. The yield percent of the extracted corn and cassava starch is 5.71 and 14.32 %. The physicochemical properties of prepared starch such as pH, moisture content, ash content and bulk density were detected. The bioplastic films: CS 1,2 & 3, CSSG 1,2 & 3 and CSSV 1,2 &3 were prepared by casting method with varying amount of starch powder, glycerol and vinegar. The physicochemical properties of prepared bioplastic films were evaluated by pH, moisture content, viscosity and specific gravity. In addition, the physicomechanical properties such as thickness, tensile strength, elongation at break percent and tear strength of prepared bioplastic films were also evaluated. Based on the physicomechanical properties, the ratio of starch, glycerol and vinegar (3: 0.5: 1 g/mL/mL) is the most suitable ratio for preparation of bioplastic films. The water absorption, shelf life and biodegradable ability of prepared bioplastic films were also investigated. The prepared bioplastic films were characterized by using Fourier transform infrared (FT IR) analysis. The FT IR results showed the presence of O-H, C-H, C-O-C stretching and C-O-C ring vibration of carbohydrate. The decomposition nature of prepared biodegradable films was investigated by TG DTA. The water absorption of prepared bioplastic films was determined by soaking in water for 24 hours. The biodegradable ability of bioplastic films was examined by soil burial test. The soil burial test results, CS 3 and CSS 3 bioplastic films were almost degraded after 14 days and 12 days respectively. According to the overall results, among the prepared bioplastic films; CS 3 and CSS 3 were selected and applied for production of food container: cups, boxes, spoons and forks, etc. In this study, the raw materials used for preparation of bioplastic films were natural, renewable resources and environmental friendly and showed biodegradation, and thus proving to be a good alternative to the conventional plastics. | ||||||
