Stretch wrap films are used to hold goods to pallets during storage and shipping. Multilayer stretch wrap films are provided herein with at least one outer layer of polypropylene and other layers of blends of polyethylenes. In preferred embodiments, stretch wrap films comprise a cling layer comprising a heterogeneously branched ultra low density polyethylene, a non-cling layer, and at least one core layer comprising linear low density polyethylene and low density polyethylene. Preferred embodiments of films of the present technology optimize physical properties enabling the film to have sufficient cling while creating a tolerable noise level upon unwinding. The optimized properties can include good clarity, high load containment, high puncture resistance, high stretch and good tear resistance.
