Poly lactic acid (PLA) is well known aliphatic poly-esters derived from corn and sugar beets, and degrades into nontoxic compounds in landfill. Melt blending of poly lactic acid and linear low density polyethylene (LLDPE) was performed in an effort to toughen polylactic acid. Melt blending of linear low density polyethylene (LLDPE) and polylactic Acid (PLA) and Low density poly ethylene (LDPE) were performed in a twin screw extruder with post extrusion blown film. The blend compositions were optimized by mechanical properties. On the basis of this, LLDPE 80 wt % LDPE 20 wt% and 1-4 wt% poly lactic acid (PLA) were found to be an optimum composition. The blends were characterized according to their mechanical and optical behavior. This blend may be used for packaging application.
