Patent ID: 8080294

Claim:
A biaxially oriented film comprising at least one core layer comprising a blend of: from 40 to 60 wt %, by weight of the core layer, of a first linear low density polyethylene (“LLDPE”) having a molecular weight distribution (Mw/Mn) within the range of from 1.0 to 4.0, a density within the range of from 0.890 to 0.920 g/cm 3 and a melt index (ASTM D1238, 190° C./2.16 kg, “I 2 ”within the range of from 0.1 to 4.0 dg/min; and from 60 to 40 wt %, by weight of the core layer, of a second LLDPE having a molecular weight distribution (Mw/Mn) within the range of from 1.0 to 3.5, a density within the range of from 0.900 to 0.935 g/cm 3 and an I 2 within the range of from 0.5 to 10.0 dg/min; and from 0.1 to 15 wt %, by weight of the core layer, of a HP-LDPE; wherein the density of the second LLDPE is greater than the density of the first LLDPE by at least 0.002 g/cm 3 ; and/or the I 2 of the second LLDPE is greater than the I 2 of the first LLDPE by at least 0.5 dg/min, and the film has a haze value of less than 10%.
