Abstract
This invention relates to a single-sided cling stretch wrap film wherein the A layer exhibits a high cling force. The opposite surface is cling-free and is fabricated from a polyolefin having a MFR less than or equal to 10.0. A particularly preferred film is an A/B/C thermoplastic film of high tensile strength. Pallet loads overwrapped with the film are neither torn or destroyed when separated from each other. The cling-free layer may contain a medium or high density polyethylene. The productivity in the fabrication of the polyolefin film is improved by the use of medium or high density polyethylene.
