Beschreibung
Zusammenfassung:	The present invention is directed to a process for making a low coefficient of friction (COF) high gloss polyolefin bottle by the following: a) adding a high gloss metallocene polyethylene during a manufacturing process on the outer layer of a container; b) adding a slip agent on the outer layer of the container wherein the container has a gloss range greater than 60 gloss units with a coefficient of friction of less than 0.25. La présente invention concerne un procédé de fabrication d'une bouteille de polyoléfine à brillance élevée et faible coefficient de frottement (COF), qui consiste à mettre en oeuvre des étapes suivantes : a) ajouter un polyéthylène métallocène à brillance élevée, pendant un processus de fabrication, sur la couche extérieure d'un récipient ; b) ajouter un agent glissant sur la couche extérieure du récipient, ledit récipient présentant une gamme de brillance supérieure à 60 unités de brillance, et un coefficient de frottement inférieur à 0,25.
