Teff is a unique staple food in Ethiopia. Teff has not been investigated in detail with respect to biofilm base material. In this study, a biofilm was prepared using teff-starch. Further, water barrier, mechanical, and optical properties of the teff-starch based films were investigated. These properties were compared with the cassava-starch based biofilm that was developed with same combination of plasticizer, surfactant and agar. The result showed that teff-starch based edible film is good compactable for food packaging material. Also, the mechanical and optical properties compared with standard cassava-starch based biofilm showed teff-starch films are better appropriate as for a packaging material.
