Abstract:
A process for preparing a film, said process comprising:(a) blending (i) from about 20 wt % to about 80 wt % of a high-molecular weight, medium density polyethlene that has a density within the range of about 0.92 to about 0.94 g/cc, an MI2 within the range of about 0.01 to about 0.5 dg/min, an MFR within the range of about 50 to about 300, and a multimodal molecular weight distribution comprising a low-molecular weight component and a high-molecular weight component wherein the low molecular weight component has an MI2 from about 50 to about 600 dg/min and a density from about 0.94 to about 0.97 g/cc; and (ii) from about 20 wt % to about 80 wt % of a linear low-density polyethylene that has a density within the range of about 0.90 to about 0.93 cc/g and an MI2 within the range of about 0.5 to about 50 dg/min; (b) converting product of step (a) into a film; and (c) orienting the film of step (b) uniaxially in the machine direction.
