Methods for improving multimodal polyethylene and films produced therefrom

摘要

A blown film composition including a first high density polyethylene component and a second high density polyethylene component, wherein the blown film contains a mixture of three or more discrete molecular weight distributions, and wherein the second high density polyethylene component has at least one more discrete molecular weight distribution than the first high density polyethylene component.

1. A composition comprising:
a first polyethylene component; a second bimodal or multimodal polyethylene component, wherein the first polyethylene component has a density ranging from 0.880 g/cm3 to 0.940 g/cm3, wherein the second polyethylene component has a density ranging from 0.880 g/cm3 to 0.940 g/cm3, or wherein the first polyethylene component and the second polyethylene component have densities ranging from 0.880 g/cm3 to 0.940 g/cm3; and a polyethylene compatible nucleating agent.
