Abstract: A laminate composite material comprises a layer of an open weave supporting fabric having a layer of breathable resin adhered thereto by an extruded layer of a thermoplastic resin blended with a high temperature volatile particulate. The resultant composite material is substantially impervious to air and water and permeable to water vapor and having a water vapor transmission rate exceeding one (1) perm of water vapor.

Abstract: A flame retardant composite sheathing including a core layer, having a plurality of superposed layers of a water-resistant paperboard adhered together by layers of an adhesive positioned intermediate and contacting adjacent said layers of water-resistant paperboard, a first layer of a polyolefin adhered to a major surface of the core layer, a metal foil adhered to the first layer of polyolefin, a second layer of a polyolefin adhered to the metal foil, and a layer of water resistant liner board adhered to the second layer of polyolefin.
Abstract: The present invention provides for improved polyolefin cling/slip stretch wrap films having superior load retention, elongation, tear resistance and puncture resistance properties and for the methods of using those stretch wrap films. The stretch wrap films are preferably constructed in a multilayer fashion having an outside cling layer, an outside slip layer, at least one inside puncture resistant layer comprising a metallocene-catalyzed polyethylene resin, and at least one inside transverse direction tear resistant layer.
