Each of the sheets or labels includes a core layer and opposed, upper and lower outer skin layers. The upper outer skin layer includes a polyolefin polymer as the predominant component, by weight, thereof and is capable of receiving printed indicia thereon. The core layer includes a polyolefin polymer as the predominant component, by weight, of the core layer; preferably a high crystallinity polypropylene homopolymer. The lower outer skin layer includes a polyolefin polymer as the predominant component by weight therein; the improvement wherein the lower outer skin layer includes a blend of organic and inorganic antiblocking agents or a blend of inorganic antiblocking agents; the blend including less than 10%, by weight, of the lower outer skin layer.
