Abstract
A surgical covering material formed by extruding a sheet, either by a blown film or a cast film process. The upper exposed layer of the material is made by using a foaming agent to create elongated depressions that are surrounded by raised areas. The alternating raised and depressed areas provide the material with a coefficient of friction that compares well to standard drape materials that include a non-woven layer. The raised and depressed areas also provide the material with hydrophilic and non-glare properties that make is a highly effective drape or covering material for use in making mayo stand covers, back table covers and patient drapes. The size and shape of the depressions may be varied to create materials of different toughness or tearability, and differing materials may be combined to form customized drapes with the ability to gain access or make pathways through the drape.
