Abstract
The present invention relates to a monolayer film comprising a mixture of a first linear polyethylene having a density in the range of from 0.926 to 0.970 g/cm; a second LLDPE having a density in the range of from 0.868 to 0.920 g/cm; and a nucleating agent to get to a better balance of low WVTR and dart while still allowing film production from it on standard monolayer equipment without need for co-extrusion capability. The LLDPE with the higher density is further characterized by having at least 57 percent (by weight of that component) of molecules having a weight average molecular weight in the range of 31,000 g/mole to 1,000,000 g/mole. These components are blended in various ratios ranging from 50 to 90% of the higher density LLDPE, 10 to 50% of the lower density LLDPE and at least 50 ppm of the nucleating agent.
