Abstract:
A stretch wrapping process comprising: at a film unwinding speed of up to about 70 meters per minute, unwinding and stretching a roll of the film comprising a composition comprising:(a) from about 80 to about 99 weight percent based on the total weight of the composition of a linear ultra low density polyethylene having a density of less than about 0.916 g/cm3; and (b) from about 1 to about 20 weight percent based on the total weight of the composition of a propylene polymer comprising 0 to about 40 weight percent olefin comonomer units having 2 to 10 carbon atoms, based on the total weight of the propylene polymer and from about 60 to about 100 weight percent propylene, based on the propylene polymer, wherein the propylene polymer has a Brookfield Thermosel viscosity of from about 1 to about 30,000 mPaÂ·s at 190Â° C. and a needle penetration of from about 5 to about 300 dmm, determined according to ASTM, at 23Â° C., wrapping said stretched film about the girth of a unitized plurality of goods, forming at least one region wherein the stretched film is wrapped about itself, overlapping layers of said film being held together by cling force.
