Abstract: The mixtures blended with starch, PE and cellulose in different proportions, were extruding processed by a twin-screw extruder. The effects of screw speed, barrel temperature, the content of plasticizer and the content of filler on tensile property of the products was investigated by response surface methodology, and a regression equation was built up. The results showed that tensile property was influenced significantly by screw speed and barrel temperature. When the screw speed parameters is 100.73 r·min-1, the extrusion temperature is 118.14 ℃, the foaming agent content is 2.75, the filler content is 5.62, the biggest tensile property is obtained.
