ABSTRACT:
A multilayer shrink film and methods of making same comprising one or more polyethylenic layers, one or more polystyrenic layer and polystyrene compatibilizing layers situate between each polyethylenic layer and polystyrenic layer wherein the polystyrene compatibilizing layers comprise less than 1% by weight substantially random interpolymer. The multilayer shrink films of the invention are produced using film biaxial orienting means.
