SHEET MATERIAL WITH ANTI-SLIP SURFACE

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 poly- mer resin affixed to the coating by a melt bond or they may be organic or inorganic particles partly embedded in the coating. The sheet mate- rial 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.
