“…This result is in agreement with previous reports on gelatinbased films [2,37] . Both studies indicate that protein-based films are considered to have high UV barrier properties, owing to their high content of aromatic amino acids, which absorb UV light.…”

“…Gelatin films prepared from Atlantic halibut skin and whey protein were completely soluble in water (Carvalho et al, 2008;Kim & Ustunol, 2001). Water solubility of 83.3% in catfish skin gelatin films and 91-96% in cuttlefish skin gelatin films were also reported by some workers (Hoque et al, 2011;Jiang, Liu, Du, & Wang, 2010), which is more or less similar to our observations. The addition of MMT had reduced the water solubility with about 20% in grouper gelatin films.…”

“…Yet, due to their hydrophilic features, they are not such good barriers to water vapor 2, 4–11. As a consequence, several strategies have been proposed to improve the moisture resistance of gelatin–based films including chemical, physical, and enzymatic crosslinking6–8, 12–15 and compositing with other moisture resistant polymers and biopolymers 9, 16–20. Another way of overcoming such drawback is by creating multilayer structures.…”

Glycerol-plasticized gelatin (Ge-30Gly) and poly(lactic acid) (PLA) films were prepared by heat-compression, molded, and then piled to produce a biodegradable three-layer sheet with PLA as outer layers and Ge30Gly as the inner layer. Lamination with PLA increased the moisture resistance and reduced the total soluble matter with respect to a single gelatin layer, while keeping transparency. The tensile strength of the multilayer sheet (36.2464.27 MPa) increased 16 folds when compared to that of Ge-30Gly. Lamination also exerted beneficial effects on the barrier properties. ) was reduced with respect to that of neat PLA, and the value obtained was comparable to that of Ge-30Gly layer. The presence of plasticized gelatin in the multilayer increased the energy at crack initiation (1.4 6 0.3 JÁm À1) with respect to that of PLA. The improvement attained in all these properties was ascribed to the good compatibility and adhesion of the individual layers featured through hydrogen interactions between the carbonyl group from PLA and the hydrogen from the peptide bonds in gelatin. Compatibility was corroborated by scanning electron microscopy observations at PLA/Ge30Gly interface and by the absence of additional peaks in the tan d curve of dynamic-mechanical analysis.
