Abstract
Modern food packaging no longer only plays a passive role in protecting and selling food, but actively changes the state of the packaged food in order to extend its shelf life. From that aspect, packaging based on cellulose, TEMPO-oxidized cellulose nanofibrils (TOCN), and chitosan, has great application potential. In this work, ultra-thin films (thickness below 100 nm) based on cellulose, TOCN, and chitosan were made to serve as a general model for packaging based on cellulose, TOCN, and chitosan. Using a quartz crystal microbalance with dissipation (QCM-D), it was investigated how TOCN coating affects the water absorbance capacity of cellulose-based ultra-thin films, as well as at which pH values greater chitosan adsorption occurs on ultra-thin films based on cellulose and TOCN. The bio-activity of the multilayered thin films was evaluated in vitro against Staphylococcus aureus and Escherichia coli. The multifunctionality comprising high water absorbance capacity and antimicrobial activity, recommend such polysaccharide-based thin films for food packaging applications
