Increase in Moisture Barrier properties of Alginate-based Films by Composting with Fatty Acids and CaCl₂ Treatment

Increase in water vapor barrier properties of sodium alginate films was by preparing composite films with fatty acids, i.e., lauric, palmitic, stearic, and oleic acids, and by treatment with 3% CaCl₂ solution for 3 min. Film thickness, surface color, microstructure, tensile strength (TS), elongation...

Summary:Increase in water vapor barrier properties of sodium alginate films was by preparing composite films with fatty acids, i.e., lauric, palmitic, stearic, and oleic acids, and by treatment with 3% CaCl₂ solution for 3 min. Film thickness, surface color, microstructure, tensile strength (TS), elongation at break (E), water vapor permeability (WVP), water solubility (WS), and sorption isotherm of films were investigated. Microstructure of films observed with SEM was changed by fatty acid and CaCl₂ treatments.
