The recycling of plastics is currently one of the most significant industrial challenges. Due to the enormous amounts of plastic wastes generated by various industry branches, it is essential to look for the potential methods of their utilization. Nevertheless, for the efficient application of recycled materials it is crucial to analyze their performance. Therefore, in presented paper we investigated the processing (melt flow index), as well as the mechanical (static tensile tests) and thermal (thermogravimetric analysis, differential scanning calorimetry) properties of four recycled low-density polyethylene streams obtained from the market. The impact of the impurities on the performance was analyzed.
