Polymeric wrapping material
A wrapping material having three distinct polymeric layers interfaced with a woven polymeric scrim is disclosed. A first polymeric layer is formed by extruding a first polymeric coating onto the scrim. A second polymeric layer and a third polymeric layer are simultaneously formed by co-extruding a second polymeric coating onto the scrim and a third polymeric coating onto the second polymeric coating.
