Physical and chemical modifications of cellulose fibers for food packaging applications

Cellulose fibers have gained considerable interest for use as gas barriers and reinforcing fillers in food packaging materials because of their interesting properties, including biodegradability, low density, nontoxicity, cost. Although modifications cellulose nanomaterials applications been reviewed the literature, they suffer from a lack comparative results, related to not covered yet. This study reviews physical chemical methods used improve oxygen water barrier uptake, mechanical strength, transparency different films nanomaterials, provides results. Heat treatment, esterification, TEMPO-mediated periodate oxidation are most common properties free-standing, bilayer, composite prepared nanomaterials. Modification using silane compounds is well-established method improving polymer films.
