Summary: | The present invention relates to oriented, multilayer polyethylene films. In one aspect, a biaxially oriented, multilayer polyethylene film comprises at least one layer comprising: (1) a polyethylene-based composition that comprises: (a) at least 97% by weight, based on the total weight of the polyethylene-based composition, of a polyethylene composition comprising: (i) from 25 to 37 percent by weight of a first polyethylene fraction having a density in the range of 0.935 to 0.947 g/cm3 and a melt index (I2) of less than 0.1 g/10 minutes; and (ii) from 63 to 75 percent by weight of a second polyethylene fraction; wherein the polyethylene composition has less than 0.10 branches per 1,000 carbon atoms when measured using 13C NMR, wherein the density of the polyethylene-based composition is at least 0.965 g/cm3, and wherein the melt index (I2) of the polyethylene-based composition is 0.5 to 10 g/10 minutes. |
