Title
(EN) EXTRUSION-MOLDED HOLLOW CONTAINER MADE OF POLYOLEFIN
(FR) RECEPTACLE CREUX EN POLYOLEFINE MOULE PAR EXTRUSION
Abstract
(EN)
An extrusion-molded hollow container made of polyethylene which comprises a high-density polyethylene layer and formed on the outer side thereof a layer comprising a copolymer of a polycyclic olefin. The layer on the outer side of the high-density polyethylene layer has a satisfactory luster and has been formed without using an adhesive. Therefore, the container has an excellent appearance and the outer layer can be recovered and recycled together with the high-density polyethylene.
(FR)
L'invention concerne un réceptacle creux en polyéthylène moulé par extrusion, comprenant une couche de polyéthylène haute densité dont la face externe est recouverte d'une couche comprenant un copolymère d'oléfine polycyclique. La couche présente sur la face externe de la couche de polyéthylène haute densité présente un brillant satisfaisant et a été formée sans adhésif. Ce réceptacle présente par conséquent de bonnes qualités esthétiques et la couche externe peut être récupérée et recyclée conjointement au polyéthylène haute densité.
