Abstract:
A film comprising a polymer blend of: (a) 0.15 to 0.8 wt % of an LDPE having an MI of 0.1 to 0.6 dg/min; and (b) 99.2 to 99.85 wt % of an LLDPE produced with a single-site catalyst comprising a metallocene and having a haze (HZlldpe), dart impact (DIlldpe), MD-Tear (MDTlldpe), and a slice long chain branching index of at least 0.90 for any portion of the composition having a molecular weight of 100,000 or above, wherein the film has a haze (HZblend), a dart impact (DIblend), and an MD-Tear (MDTblend), and HZblend=a*HZlldpe, where a is 0.20 to 0.70; DIblend=b*DIlldpe, where b is 0.9 to 1.3; and MDTblend=c*MDTlldpe, where c is 0.8 to 1.1.
