HPMC films are generally brittle in nature, so a plasticizer such as glycerol is added to improve the flexibility of films. However, plasticized HPMC films have still shown to be a poor moisture barrier due to their hydrophilic biopolymers. Incorporation of lipids and oil makes films insoluble. Lipids such as beeswax have been shown to reduce the water vapor permeability (WVP) when the beeswax was incorporated in HPMCelipid composite coated paper and the lowest weight loss was in chitosanebeeswax coated strawberries
