Patent ID: 10836889

Abstract:
Disclosed herein is a polyethylene composition which includes 45% to 95% by weight of a metallocene-catalyzed polyethylene A. The polyethylene A has a density ranging from 0.916 g/cm3 to 0.940 g/cm3, and a melt index MI2 of at least 1.5 g/10 min to at most 4.0 g/10 min. The polyethylene composition has at least 5% to at most 55% by weight of a metallocene-catalyzed polyethylene B. The metallocene-catalyzed polyethylene B includes 45% to 75% by weight of a metallocene-catalyzed polyethylene B1. The polyethylene B1 has a density of at most 0.918 g/cm3, a melt index MI2 lower than the melt index MI2 of polyethylene A, and includes 25% to 55% by weight of a metallocene-catalyzed polyethylene B2. The density of polyethylene B2 is higher than the density of polyethylene B1. The melt index MI2 of polyethylene B2 is higher than the melt index MI2 of polyethylene B1.
