ABSTRACT The correlation between mechanical and Theological properties of low-density polyethylene (LDPE) waste and LDPE/HDPE (high-density polyethylene) waste blends with different degrees of degradation has been investigated. To predict the suitability of PE wastes for a blown-film extrusion process, parameters such as melt flow index, morphology of the extrudate's surface, and melt elongation at break were determined. For the binary blends of LDPE/HDPE waste, the melt flow index ratio of the components was also used. Blown-film extrusion of this PE waste is possible only within the defined critical values of these parameters.
