Abstract: Blends of recycled agriculture films (RPE) and Ethylene-vinyl acetate (EVA) were prepared by the twin-screw extruder at different ratios and pelletized. RPE served for matrix in this work. Virgin low density polyethylene (LDPE) was used as a contrast. The blends were blowed into thin films by single-screw extrusion. Mechanical and rheological properties of the blends were carefully evaluated and compared with virgin LDPE. The results show the tensile properties of the blends changed a little and elongation at break increased dramaticlly with the addition of EVA. The elongation at break and tensile properties of films made by RPE/EVA(50/50) blend was similar to virgin LDPE. The rheological properties of RPE have improved. The blends show potential applications in good performance products.
