HEAT SHRINKABLE PACKAGING FILM WITH IMPROVED HOT SLIP PROPERTIES

摘要

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.
