Abstract

A slip control sheeting comprising a backing having first and second major surfaces with an array of protrusions on the first major surface and at least one of (1) a layer of adhesive on the second major surface and (2) a reinforcing web at least partially embedded in the backing. The protrusions are pyramids with triangular bases having a height between about 3 and 21 mils and the array is defined in part by a pattern of three intersecting sets of parallel grooves formed in the first major surface, the grooves defining three major axes of the sheeting.
