EF2002 is a low-density polyethylene (LDPE) with high molecular weight. Has excellent processability, proper of branched polyethylene produced by a high-pressure process. EF2002 resin presents an excellent performance in conventional LDPE extruders, granting low energy consumption during the whole process and allowing the production of packaging with a good dimensional uniformity and an excellent surface finishing.
Application: High resistance films for industrial packaging, heavy duty bags and plastic canvas. Base resin for agriculture films with big dimensions.
Process: Blown Film Extrusion
