On the Evaluation of Flow Properties Characterizing Blown Film Extrusion of Polyolefin Alternatives. [PDF]
Polymers (Basel)The lower melt strength of biodegradable materials in comparison to low density polyethylenes raises serious issues regarding their processability via blown film molding. Thus, reliable rheological characterization is a viable option for assessing their efficient flow performance.

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 ...
