Abstract

A composition comprising from 10 wt % to 86 wt % of an ethylene component including at least one ethylene based polymer having an ethylene content of at least 50.0 wt %, a melt index from 0.1 g/10 min to 100.0 g/10 min, and a density from 0.935 g/cm3 to 0.965 g/cm3; from 10 wt % to 86 wt % of a propylene component including at least one propylene based polymer having a propylene content of at least 50.0 wt % and a melt flow rate from 0.5 g/10 min to 200.0 g/10 min; from 2 wt % to 22 wt % of an octene component including at least one octene based polymer having an octene content of at least 80 wt %; and from 2 wt % to 20 wt % of a composite component including at least one selected from the group of a crystalline block composite and a specified block composite, derived from at least ethylene and an alpha-olefin.
