According to recent research from the United States, "Starch plasticized with water, glycerol, and stearic acid was extruded and sheeted into films 0.4-0.6 mm thick. The ingredients were extruded in a conical twin-screw extruder at a temperature profile of 50-120-120-120 degrees C and a screw speed of 45 rpm."
"The effects of glycerol, water, and stearic acid on selected physical and functional properties of the films were studied. The tensile strength, tensile strain at break, and Young's modulus were 0.23-2.91 Mpa, 45.79-90.83%, and 2.89-3.94 MPa, respectively. Differential scanning calorimetry thermograms exhibited two glass transitions and multiple melting ...
