Evaluation and Optimization of Sustainable Ecofriendly Bio-based Micro-composites for Smart Packaging Application Using Micro-Clay Particles as Reinforcement

Because of its environmental friendliness and easy decomposition, biodegradable plastics have gained immense popularity as a packaging material. However, traditional petroleum-based plastics have been found to have negative impacts on the environment, leading to a surge in demand for biodegradable bioplastics. While bioplastics made from starch are a viable option, they lack mechanical strength and thermal stability in the absence of fillers. In order to overcome this limitation, researchers focused on creating a robust and degradable bioplastic using cassava root and mango seed kernel, reinforced with micro-pottery clay. Based on the present analysis, the optimum tensile strength of the product was found to be 5.66 ± 0.012 Mpa. Based on the present findings, the product optimal conditions were observed at 0.25 g w/w micro-clay content to starch ratio and 1.25 w/v glycerol concentration. The physicochemical and thermomechanical properties of the micro-composite film were significantly influenced by both clay particle and plasticizer concentration. Additionally, the degradation rate of the films was studied using soil burial, and it was found to be highest at a plasticizer concentration of 1.75 ml and lowest at a micro-clay content of 0.5 g.
