The objective of this study was to investigate the effect of different glycerol concentrations (15, 30, 45, 60 & 75% w/w of methylcellulose) and film thickness (15, 30 & 60µm) on methylcellulose (MC) films water vapor permeability and mechanical properties. Finally, 15µm films containing 45% glycerol (the best conditions) were selected. Results showed the significant effect of glycerol concentration on films water vapor barrier and mechanical properties. Film thickness affected WVP and tensile strength but not elongation at break.
