Novel biobased multicomponent edible films from hydroxypropyl methylcellulose (HPMC) and grapeseed oil (GsO) are developed. This study investigates the effect of GsO concentration on some physical and physico‐chemical properties of the films. The hydrophobicity of the films increases, which is expressed in improved water vapor permeability and reduced moisture absorption. Color and penetration properties of the films are also investigated. The pure cellulose film is almost colorless, but it becomes darker with pale greenish yellow color from the grape seed oil. The break force of the films is independent from the grape seed oil concentration, but the break deformation and the deformation work of the films with GsO is much higher and these are more elastic. Finally, multicomponent films demonstrated strong antioxidant activity. The obtained results suggest that the new multicomponent films may be used as food active packaging.
