Abstract: The invention relates to a method for producing polyolefin recyclates, in particular HDPE recyclates. In a specified sequence, color-mixed polyolefin-containing groups are washed at a low temperature, washed at an increased temperature in an alkaline medium, flake-sorted, and treated at an increased temperature in order to remove migration materials. By virtue of the aforementioned method, polyolefin recyclates can be obtained with a substantially improved degree of purity compared to hitherto commercially available recyclates, said recyclates being usable in the production of novel consumer product packaging. Additionally, unpleasant odors connected to known polyolefin recyclates due to the decomposition products of migration materials formed during the extrusion process are largely prevented.
