<p>In-mold rotomolding labels comprise a printed sheet and a "cover stock" layer that covers the printed sheet and also provides adhesion of the label to the mold prior to the rotomolding procedure. The cover stock is prepared from a high melting polyethylene and a low melting polyolefin and is characterized by having a non-homogeneous morphology in which discrete "islands" of the polyethylene are present in a continuous "sea" of the polyolefin. The cover stock melts during the rotomolding process to provide a protective cover for the label graphics.</p>
