Starch-based films have promising application on food packaging due to their outstanding performance with flexibility and transparency. On the other hand, the mechanical properties of starch films should be improved. The aim of this work is to enhance the mechanical performance of starch films by reinforcing the films with flaxseed meal (flaxseed fiber and protein). Films were prepared by casting technique, from film-forming suspensions of rice starch, flaxseed meal, glycerol and water. The dynamic mechanical method was used for measurement of the starch film samples. Films reinforced with flaxseed meal showed higher tensile strength, lower deformation capacity and higher the glass transition temperature (Tg) than films without flaxseed meal.
