A polymer blend comprises a propylene-based homopolymer or copolymer in an amount of from 75 to 95 weight percent, and an olefin block copolymer (OBC) in an amount of from 5 to 25 weight percent, based total blend weight. The polymer blend, and films having outer printed layers containing the blend, provide enhanced ink abrasion resistance. The OBC is an ethylene/α-olefin copolymer having hard and soft segments. Multilayer film made using the blend can be used for food packaging, and may optionally be heat shrinkable. |
