SHRINK FILM

摘要

A multi-layer shrink film. The shrink film can exhibit a significant amount of shrink within a certain temperature range that is above the onset temperature of the film. The film can exhibit a shrinkage that is at least about 50% of the total shrink within a temperature range T1 above the onset temperature of the film. In one aspect, the shrink film comprises a core layer and skin layers disposed about opposite surfaces of the core layer, and tie layers disposed between the core and the skin layers, the skin layers individually comprising a polyester, e.g., a glycol-modified polyester, and the tie layers individually comprising an anhydride modified material.
