Table 1 lists the water contact angles of the different films, and it is seen that the films of pure gelatin and the blends containing up to 50% starch have similar water contact angles. The results indicate that gelatin is a continuous phase, while starch is a separated phase distributed in gelatin and covered by gelatin in all the blends.The starch has smaller water contact
angle than gelatin indicating that the starch is more hydrophilic
