Abstract

A heat-shrinkable film comprises a blend of 35-75 wt % of an ethylene-based polymer, 10-45 wt % of an ethylene/unsaturated ester copolymer, and 5-30 wt % of a plastomer, with the blend making up at least 20 wt % of the film. The ethylene-based polymer has a peak melt point ≥95° C. The plastomer has a peak melt point ≤90° C. and a melt index of ≤1.1 g/10 min. The film comprises a cross-linked polymer network which has been strained by solid state orientation. The film has a total free shrink at 85° C. of at least 90% and an energy-to-break of at least 0.70 J/mil.
