Effect of plasticizer and antimicrobial agents on functional properties of bionanocomposite films based on corn starch-chitosan for food packaging applications.The aim of this study was to evaluate the influence plasticizer (glycerol (GLY)/sorbitol (SOR)) and antimicrobial (potassium sorbate (KS)/grapefruit seed extract (GFSE)) agents on crystallinity, water barrier, mechanical, thermal and anti-fungal properties of prepared with corn starch (CS)-chitosan (CH) nanoclay (Na-MMT) bionanocomposite films.  Films plasticized with SOR showed the highest tensile strength, lowest film solubility, lowest water vapor permeability and thermal stability.
