A polymer blend composition comprising: (a) from 0.5 to 99 percent by weight, based on the total weight of (a), (b), and (c), of an aliphatic alpha -olefin homopolymer or interpolymer, or an interpolymer of an alpha -olefin and a non-aromatic monomer interpolymerizable therewith; (b) from 0.5 to 99 percent by weight, based on the total weight of (a), (b), and (c), of a homopolymer or interpolymer of monovinylidene aromatic monomers, or an interpolymer of monovinylidene aromatic monomer and a monomer interpolymerizable therewith other than an aliphatic alpha -olefin; and (c) from 0.5 to 99 percent by weight, based on the total weight of (a), (b), and (c), of a substantially random interpolymer comprising an alpha -olefin and a vinylidene aromatic monomer. An expandable composition, comprising such polymer blend composition and an expanding agent; a foamed composition obtained by subjecting such an expandable composition to a foaming process; an article of manufacture molded from such a polymer blend composition; and a method of packaging using such a polymer blend composition.
