ABSTRACT:
An improved stretch/cling film suitable for pallet wrap, produced by the blown film process exhibits superior performance qualities similar to stretch cling film produced by the cast film process, but with an improved tear resistance; such film has reduced noise characteristics. The film of the invention is produced by blending 40 to 80% by weight linear low density polyethylene polymerized with an .alpha.-olefin comonomer having a melt index range of 0.8 to 1.2 and a density range of 0.916 to 0.920; with 60 to 20% by weight of a flexible semi-crystalline polyethylene with a melt index 0.8 to 2.0 and a density of 0.86 to 0.91; with 3 to 9% by weight liquid polyolefin and 0.1 to 4.0% by weight of a surfactant. The films of the invention exhibit a two-sided cling.
