Abstract[English] Polymeric compositions including recycled polyethylene, methods of making the compositions, and articles containing the compositions are described. In some embodiments, the polymeric compositions can contain 10 wt.% to 30 wt.% recycled polyethylene; 50 wt.% to 80 wt.% an ethylene alpha-olefin copolymer; and 5 wt.% to 25 wt.% high density polyethylene. In some embodiments, at least 70 wt.% of the article comprises the polymeric composition.[French] L'invention concerne des compositions polymères comprenant du polyéthylène recyclé, des procédés de fabrication des compositions, et des articles contenant les compositions. Dans certains modes de réalisation, les compositions polymères peuvent contenir de 10 % en poids à 30 % en poids de polyéthylène recyclé ; de 50 % en poids à 80 % en poids d'un copolymère d'éthylène alpha-oléfine ; et de 5 % en poids à 25 % en poids de polyéthylène haute densité. Dans certains modes de réalisation, au moins 70 % en poids de l'article comprend la composition polymère.
