Abstract
Embodiments are directed towards polyolefin compositions including a high molecular weight polyolefin and a low molecular weight polyolefin.
Claims9
A polyethylene composition comprising:
- a first polyethylene having a density from 0.920 to 0.945 g/cm3 wherein the first polyethylene is an ethylene/1-hexene copolymer that has a high load melt index (I21) from 0.45 to 1.50 g/10 min.;
- and
- a second polyethylene having an I2 from 5 to 200 g/10 min,
- wherein the polyethylene composition has a first polyethylene split of from 39 to 49 weight percent and a cumulative detector fraction (CDFLS) at a molecular weight of ≥10,000,000 g/mol of greater than 0.085, further wherein the polyethylene composition exhibits one or more of:
- (i) an absolute Z-average molecular weight (Mz(Abs)) from 3,500,000 to 12,000,000 g/mol;
- or
- (ii) an absolute weight average molecular weight (Mw(Abs)) from 350,000 to 800,000 g/mol.
