Abstract
Multilayer shrink films and methods of making same that are substantially free of silicone. The multilayer shrink films of the invention are produced using film biaxial orienting means, have haze values of 5 or less and Young's modulus of 40,000 psi or greater and superior hot slip properties. Cyclic-olefin copolymer (COC) is used in the outermost layers to impart superior hot slip. Preferably the film comprises large proportion of linear low density polyethylene (LLDPE) or ethylene propylene butane terpolymer. Suitable COCs for use in the invention are limited to single site catalyzed COC.
