Polyolefin film with improved toughness |
| abstract |
A film formed from a polyethylene copolymer using a reducing chromium oxide catalyst, ethylene monomer, and a comonomer selected from butene monomer or 1-hexene, wherein the polyethylene copolymer has a density of about 0.935 to about 0.950 g/cm 3 and I 21 /I 5 in the range of about 18.0 to about 30.0. Films formed from the polyethylene copolymer have significantly greater dart impact strength (g/μm) than polyethylene copolymer films formed using a silyl chromate catalyst in place of the reducing chromium oxide catalyst . Methods of making such membranes are also provided. |
