Bionanocomposite films of nanocellulose with chitosan or alginate: Enhanced barrier properties and active packaging potential

Key Points

• Enhanced barrier properties are observed in films containing nanocellulose and chitosan or alginate, benefiting packaging applications.
• Key findings indicate a significant increase in moisture and gas barrier performance in the tested films, aiding food preservation.
• The study employs a comparative analysis of bionanocomposite films regarding different concentrations of chitosan and alginate.
• Results support the potential for active packaging solutions, benefiting food sustainability and shelf life, but may require further optimization.
