Title
(EN) HIGH-DENSITY POLYETHYLENE FOR CAPS AND CLOSURES
(FR) POLYÉTHYLÈNE HAUTE DENSITÉ POUR BOUCHONS ET CAPUCHONS
Abstract
(EN) The present invention relates to an improved high-density polyethylene (HDPE), particularly adapted for the manufacture of caps and closures, which may for example be used as screw-on caps for carbonated or still drinks. Hence, the present invention also relates to such caps and closures as well as to their use.
(FR) La présente invention porte sur un polyéthylène haute densité (PE-HD) amélioré, particulièrement conçu pour la fabrication de bouchons et capuchons, qui peuvent par exemple être utilisés comme bouchons à vis pour des boissons gazeuses ou plates. Donc, la présente invention porte également sur de tels bouchons et capuchons ainsi que sur leur utilisation.
