Polar thermoplastic polyolefin blends are provided which are flexible and are particularly useful in replacing polyvinyl chloride sheeting used as liners, folders, etc.. The blends comprise, in general, a non-polar thermoplastic polyolefin, a polar ethylene copolymer, an epoxy functionalized polar ethylene copolymer, and a carboxylic acid or anhydride functionalized olefin polymer, all of which are chlorine-free.
