Masterbatches comprising high density polyethylene (HDPE) are used for the production of polyolefin articles, particularly films. Employing HDPE in a masterbatch alone or in combination with a hydrocarbon resin and/or a polyolefin ultimately results in extruded polyolefin articles of optimal stiffness and ductility. Employing a high density polyethylene in combination with a hydrocarbon resin and a polyolefin in a masterbatch causes the masterbatch to solidify more rapidly and be pelletized more efficiently.

Mélanges-maîtres renfermant du polyéthylène haute densité (PEHD), utilisés pour la production d'articles en polyoléfines, notamment de pellicules. L'utilisation de PEHD dans un mélange-maître, seul ou en combinaison avec une résine d'hydrocarbure et (ou) une polyoléfine, donne ultimement des articles en polyoléfine extrudée, possédant une rigidité et une ductilité optimales. L'emploi de polyéthylène haute densité en combinaison avec une résine d'hydrocarbure et une polyoléfine dans un mélange-maître permet de solidifier ce dernier plus rapidement et de le transformer plus efficacement en granules.
