Tensile Properties of Extruded Zein Sheets and Extrusion Blown Films
Macromolecular Materials and Engineering, 2003 AbstractZein‐based plastic sheets and films were formed by extrusion through a slit‐die or blowing head. Zein was plasticized with oleic acid and formed into a wet moldable mass (resin) to feed the extruders. Both single‐ and twin‐screw extruded sheets showed higher elongation at break, lower tensile strength, and lower Young's Modulus than non ...
