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.

Silicone-free multilayer shrink film for high speed packaging lines

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.

Multilayer shrink film with polystyrene and polyethylene layers

A multilayer shrink film and methods of making same comprising high speed polyethylenic outer layers along with one or more cyclic-olefin copolymer (COC) containing inner layers. 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 50,000 psi or greater and superior hot slip properties. In order to achieve the desired modulus, films of the present invention comprise from 10% to 30% COC and from 2% to 25% softening olefin copolymer. Preferably the film comprises large proportion of linear low density polyethylene (LLDPE). Suitable COCs for use in the invention are limited to single site catalyzed COC.

Multilayer shrink film for high speed packaging lines

A polyolefin woven fabric extrusion coating with superior soft tactile characteristic is disclosed comprising ethylenic elastomer and thermoplastic vulcanizate. The combination performs in a synergistic fashion to obtain more pleasing soft tactile characteristic than is available with either elastomer or thermoplastic vulcanizate alone. The inclusion of additives may enhance properties and include plastomer, UV stabilizers, flame retardant, antiblock, colorant, printable additives and polar additives.
