Preparation and characterization of PVA /cellulose nanocrystals/ ɛ-polylysine nanocomposite as potential food packaging application

The manufacture and analysis of Polyvinyl Alcohol (PVA) Cellulose Nanocrystals (CNC) ɛ-Polylysine thin films are the main focus of the thesis, with a focus towards their possible use in food packaging. The physical and chemical characteristics of the resultant thin films are thoroughly investigated as part of the research's characterisation phase. To evaluate a material's endurance, mechanical characteristics like tensile strength and flexibility, weight loss, and x-ray diffraction analysis are looked at. For food packaging materials, barrier qualities especially those related to gas and moisture permeability are vital factors to take into account. The research hopes to make a significant contribution to the field of sustainable packaging by illuminating these traits. In order to maintain the quality and safety of packaged food goods, it is necessary to fulfil both the mechanical and antibacterial needs. The objective is to offer an efficient and environmentally friendly substitute for food packaging applications.
