TLDR
In this article, a multi-layer shrink film including a skin layer, a core layer and a polyethylene based elastomer is described, with a density of below 0.96 g/cm 3 and excellent shrinkage and stiffness.Abstract:
A multi-layer shrink film (10) including a skin layer (13) and a core layer (11) is disclosed. The skin layer comprises at least 50% by weight of a cyclic olefin copolymer and the core layer comprises from 5% by weight to 50% by weight of a propylene based elastomer, from 20% by weight to 50% by weight of a propylene based plastomer, from 1% by weight to 20% by weight of a hydrocarbon resin and from 5% by weight to 30% by weight of a cyclic olefin copolymer. The multi-layer shrink film (10) exhibits a density of below 0.96 g/cm 3 and has excellent shrinkage and stiffness.read more
