Title (EN) LLDPE-BASED STRETCHABLE MULTILAYER FILMS
(FR) FILMS MULTICOUCHES ETIRABLES A BASE DE POLYETHYLENE BASSE DENSITE, LINEAIRE
Abstract:
(EN) Stretchable multilayer films in which at least one layer comprises: a) a linear low density polyethylene (LLDPE); b) a copolymer of propylene with ethylene and/or with one or more $g(a)-olefins CH2=CHRI, in which RI is an alkyl radical having from 2 to 10 carbon atoms, this copolymer being of relatively high insolubility in xylene; and c) a low density polyethylene (LDPE). The said films, which have improved optical and mechanical properties, are particularly suitable for use in the packaging sector.
(FR) Ces films multicouches étirables comportent au moins une couche comprenant: a) un polyéthylène basse densité, linéaire, b) un copolymère de propylène avec éthylène et/ou avec un ou plusieurs $g(a)-oléfines CH2=CHRI, où RI représente un radical alkyle comprenant 2 à 10 atomes de carbone, ce copolymère présentant une insolubilité relativement élevée dans du xylène, et c) un polyéthylène basse densité. Ces films possèdent des propriétés optiques et mécaniques améliorées et ils sont notamment conçus pour être utilisés dans le domaine de l'emballage.
