<p>A shrink film includes an internal layer including a styrene/butadiene/styreneblock copolymer; and first and second outer layers including an olefinic polymer.First and second intermediate layers including an ethylene copolymer havinga melt index less than 4.0 can be optionally included. Alternatively, a shrinkfilm includes an internal layer including an ehtylene copolymer having a meltindex less than 4.0; a first and second intermediate layer each including a styrene/butadiene/styreneblock copolymer; and a first and second outer layer each including an olefinicpolymer. Film of the invention has a free shrink of from 40% to 80% at 240%F, andan Elmendorf tear of from 70 grams/mil to 300 grams/mil, in at least one of the longitudinaland transverse directions.</p> |
