| Purpose: This study evaluated water vapor permeability characteristics of laminated edible films. |
| Abstract: Edible films composed of a water soluble, carbohydrate layer (hydroxypropyl methylcellulose) and various kinds of lipid layers were tested for resistance to water vapor permeability. Films were tested at 25C and a relative humidity differential of 85%. Films containing solid lipids, such as beeswax, paraffin, hydrogenated palm oil or stearic acid yielded permeabilities of 0.2 g*mil*day-1*mmHg-1 or less which is a smaller value than that for low density polyethylene. |
