Glycerol and oleic acid (OA) were incorporated into carboxymethyl cellulose (CMC) films by an emulsification method. Films containing different amounts of glycerol and OA were examined for mechanical properties, water vapor permeability (WVP), and moisture uptake, optical and thermal properties. Addition of OA to the CMC films significantly improved the barrier property. However, the effect of OA on the mechanical properties was lower than glycerol. By increasing of OA content, the cloudiness of the CMC films was intensified and Hunter value (b) of the films increased (by ca. 35.8%). (C) 2010 Elsevier B.V. All rights reserved.
