| titleOfInvention | Polyethylene films and method of making the same |
| abstract | The instant invention is a polyethylene film, and method of making the same. The polyethylene film according to instant invention includes at least one heterogeneously branched ethylene/a-olefin copolymer having a density in the range of about 0.910 to about 0.930 g/cm<3>, a molecular weight distribution in the range of about 2.8 to 3.8,, a melt index (I2) in the range of about 0.3 to about 4 g/10min, and an I10/I2 ratio in the range of 6.5 to about 7.8. The film has a normalized dart impact strength of equal or greater than (6666-7012* density) g/mil, a normalized tear strength of equal or greater than (440*e -(density-0.915)<2> / 2*(0.00949)<2>) g/mil, and a haze in the range of 3 to 10 percent. The method of making the polyethylene film according to instant invention includes the following steps: (1) providing at least one heterogeneously branched ethylene/a-olefin copolymer having a density in the range of about 0.910 to about 0.930 g/cm<3>, a molecular weight distribution in therange of about 2.8 to 3.8,, a melt index (I2) in the range of about 0.3 to about 4 g/10 min, and an I10/I2 ratio in the range of 6.5 to about 7.8; (2) processing the heterogeneously branched ethylene/a-olefin copolymer via blown film extrusion process or cast film extrusion process; and (3) thereby forming a film having a normalized dart impact strength of equal or greater than (6666-7012* density) g/mil, a normalized tear strength of equal or greater than (440*e -(density-0.915)<2> / 2*(0.00949)<2> ) g/mil, and a haze in the range of 3 to 10 percent. |
