The attention to biopolymers has risen as a result of the exhaustion of fossil fuel supply and the harm to the environment resulting from a buildup of plastic packaging that is not biodegradable. Several biopolymers have been produced from leftover food in 256order to decrease such waste while concurrently providing innovative materials used to package food. Chitosan serves as a substitute for artificial polymers and a supply of starting materials for new products. To decide if a material is suitable for use as a material for packing food, it is crucial to examine its permeability and mechanical properties. It is feasible to predict how films will react when handling, transferring, and storing packaged objects thanks to their mechanical properties. Pure chitosan films are the best choice for use in active and food packaging because of their mechanical and barrier characteristics. To alter these properties, chitosan can be mixed with plasticizers, other polysaccharides, lipids, and proteins, among other things. These mixtures maintain the biodegradability of the polymer and the food’s quality attributes while modifying the final polymer’s characteristics to meet food requirements and extend its useful life. In terms of their optical properties, pure chitosan films, which are optically transparent, demonstrate strong transmittance levels in the visible range. This is an important consideration in figuring out how well the client will respond to the videos. The remarkable UV absorbance of films based on chitosan also enables them to protect food against lipid oxidations brought on using ultraviolet rays.
