Abstract

A multilayer sheet, which is particularly well adapted for use as as a label sleeve on carbonated beverage containers, includes first and second coextruded unfoamed layers of polymer compositions each consisting essentially of polyolefin, polystyrene and a compatibility agent. The polyolefin and polystyrene are in a weight ratio in the range of about 30/70 to 70/30, and the compatibility agent is in the amount of about 5% to 10% by total weight. A pigment in the amount of about 10% to 15% by total weight may be included in one or both of the coextruded layers. The polyolefin preferably is selected from the group consisting of polypropylene, polyethylene and mixtures thereof, and the compatibility agent preferably comprises a styrene-ethylene/butylene-styrene block copolymer. One of the unfoamed layers preferably is thicker and of higher strength than the other layer, while the other layer has a smooth uniform exterior surface.
