Some properties of cassava and tree cassava films were studied and compared. Water barrier and
mechanical properties of these films were strongly influenced by glycerol content. With increasing glycerol
concentration, moisture content, water solubility and water vapor permeability of both cassava and tree
cassava films increased while tensile strength, percent elongation and Young’s modulus decreased. Tree
cassava films presented better WS and WVP values compared to those of cassava films regardless of the
glycerol content.
