ABSTRACT:
The present invention provides for improved thermoplastic stretch wrap films having superior cling force, load retention, elongation, tear resistance and puncture resistance properties and for the methods of using those stretch wrap films. The stretch wrap films generally have a thickness of from about 0.4 to about 3 mils. The stretch wrap films are preferably constructed in a multilayer fashion having outside cling layers, and at least one inside puncture resistant layer comprising a metallocene-catalyzed polyethylene resin and at least one inside transverse direction tear resistant layer comprising a polyethylene copolymer.
