Evaluation of the biodegradability, thermal stability, and mechanical properties of nanocellulose-chitosan film for food packaging

In this modern era, synthetic plastics are widely used in all around the world, causing environmental issue. An alternative material that can be used to replace synthetic plastics for food packaging are natural, biodegradable nanocellulose films manufactured from agricultural waste. Nanocellulose will be extracted from agricultural waste via acid hydrolysis, and chitosan film containing different nanocellulose content will be prepared via solution casting method. The objective of this study is to investigate the optimum ratio of chitosan to nanocellulose content to prepare the nanocellulose-chitosan film. Besides that, properties such as the biodegradability, thermal stability, tensile strength, and elongation at break of the nanocellulose-chitosan film are required to be investigated and studied using biodegradability test, thermogravimetric analyzer (TGA) and Instron tensile test, respectively. The expected outcome from this research is to be able to produce nanocellulose film that can be used to replace non-degradable plastic for food packaging.
