摘要

A sheet material for use as a wrapping material has surface areas with a high coefficient of friction to provide anti-slip properties to the wrapper. The sheet comprises a woven or non-woven scrim with a polymer resin coating on one side and particles protruding from the coating to provide the anti-slip properties. The particles may be polymer resin affixed to the coating by a melt bond or they may be organic or inorganic particles partly embedded in the coating. The sheet material may include additional coatings of resin and paper on the side of the scrim opposite to the particles. The sheet material is made by a method which includes depositing the particles on the resin coating while it is still in a molten state and feeding the coated scrim with particles through a nip between two rollers.
