Recycled polyethylene containing very small amounts of nylon-6 or PET, which is the source of flexible oil pouches, may find applications as raw materials for other polymer products after the recycled polymer is properly identified and characterized before reprocessing. Proper identification and characterization of the polymer components present in the waste has considerable importance for obtaining value-added products. In this investigation, post-use oil pouch films, collected from municipal garbage, were first subjected to sorting, washing and drying. Then the dried films were fractionated by dissolving in solvents. The isolated component polymers were characterized and identified by solvent fractionation, FTIR, DSC-TGA and WAXD analysis.
