MULTILAYER FILMS AND ARTICLES COMPRISING MULTILAYER FILMS

Embodiments of the present invention relate to multilayer films and articles. In one aspect, a multilayer film comprises at least one outer layer comprising at least 50 wt % of a polyethylene composition comprising the reaction product of ethylene and optionally, one or more alpha-olefin comonomers, wherein the polyethylene composition is characterized by the following properties: a. a melt index, I2, of from 0.3 to 3.0 g/10 min; b. a density of from 0.950 to 0.965 g/cm3; c. a melt flow ratio, I10/I2, of from 6.3 to 7.5; and d. a molecular weight distribution (MWD) of from 2.2 to 3.5, wherein the multilayer film has a thickness of at least 2 mils, wherein the multilayer film comprises at least 50% by weight polyethylene, wherein the multilayer film exhibits a surface haze of 13.5% or less when measured according to ASTM 1003-07, and wherein the multilayer film exhibit a water vapor transmission rate of 0.7 g-mil/100 in2/day or less when measured according to ASTM F1249-06 at a temperature of 38° C. and a relative humidity of 100%.
