CA 2207673

A polyolefin heat shrinkable film comprising opposed surface layers, in which at least one of the surface layers contains slip additive and in which the slip properties of the film are formed immediately on extrusion of said film. Preferably, the at least one surface layer thereof is formed from a composition of polyolefin and a micro-dispersion of an ultra-high molecular weight silicone polymer.

Un film thermo-rétrécissant de polyoléfine comprenant des couches de surface opposées dont une des couches de surface au moins contient des additifs de glissement et dont les propriétés de glissement du film sont formées dès l'extrusion du film. De préférence, au moins une couche de surface est formée à partir d'une composition de polyoléfine et d'une micro-dispersion d'un polymère de silicone de masse moléculaire très élevée.
