Gelatinized corn starch was prepared by a co-rotating twin-screw extruder,and through drying and comminuting process. Thermoplastic starch was prepared with the gelatinized corn starch powder as raw material and glycerol and Polyvinyl Alcohol as plasticizing agents. Thermoplastic starch sheet was prepared with extruding process. Degree of gelatinization was tested by a polarizing microscope. Mechanical properties of prepared thermal plastic starch sheets were studied in relating to type and amount of the plasticizing agents.
