Abstract
A polymeric composition that is suitable for use as a film or a coating. The polymeric composition comprises: (a) a first component comprising copolymer derived from ethylene and one or more C3 to C20 α-olefin comonomers. The first component has a density of about 0.911 to about 0.918 g/cm3, a compositional distribution breadth index (CDBI) of about 60% to about 85%, a melt index (MI) of about 16.0 to about 30.0 g/10 min, a molecular weight distribution (MWD) of about 1.5 to about 4.0, and a melt index ratio (MIR) of less than about 25; and (b) a second component comprising a low density polyethylene (LDPE). The second component has a g′ of about 0.8 to about 0.15 and a MI that is lower than the MI of the first component.
