Abstract

This study investigated consequent functional effects (mechanical and physical) on Gelatin/ CMC/Chitosan composite films from the addition of sorbitol. With glycerol as a plasticizer solutions for Gelatin/CMC/Chitosan composite films containing graduated sorbitol concentrations (0 0.05 0.1 0.15 0.2 25 and 30) were cast on a petri dish and oven dried at 45C. The fabricated films were then characterized for tensile strength elongation at break (EAB) and puncture resistance (mechanical properties); as well as film thickness water vapor permeability (WVP) thermal properties light transmittance and transparency (UV and visible light transmission) biodegradability and X-ray diffraction (physical properties). Results indicated that by increasing sorbitol concentration melting point and tensile strength decreased overall (p0.05) in weight loss () as sorbitol concentrations increased. The addition of 10 sorbitol to the Gelatin/CMC/Chitosan composite films under study demonstrated satisfactory mechanical properties and low water vapor penetration. Film C (10 sorbitol) demonstrated sufficient mechanical properties with 1.51 MPa for tensile strength 5.05 for EAB 6.36N for puncture force in terms of flexibility and low WVP at 3.83 g.mm/h2.Pa compared to all other formulations.
