The aim of work was the improvement of the mechanical and water barrier properties of nanocomposites prepared from fish gelatin and nanoclays (5–15%), plasticized with glycerol at different concentrations. The effect of hydrophilic Cloisite Na1 and Nanomer®PGV was compared with that exerted by organically modified more hydrophobic Nanofil®2 and NanoBent ZR-1. Antimicrobial activity of nanocomposites containing hydrophobic nanoclays was also investigated. In a nanocomposite with 5% Cloisite Na1 and 15% glycerol, the Tensile strength (TS) was by 20% higher than that for plasticized films without nanoclay. The improvement of TS was also evidenced for plasticized nanocomposites containing 5% of hydrophobic NanoBent ZR-1 and Nanofil®2. Nanocomposites containing 5% of Cloisite Na1 with 15% glycerol, and these containing 5% Nanofil ®2 or NanoBent ZR-1 with 20% glycerol, showed 23% and about 15%, respectively, lower water vapor permeability than gelatin films. Gelatin-NanoBent ZR-1 nanocomposite caused complete inactivation of gram-positive bacteria S. aureus and L. innocua.
