Abstract
Abstract A flexible, laminated packaging material is disclosed. This material -- composed, in order, of a non-woven sheet of spun-bonded polymeric filament; a metallic foil; and an inner surface ply of heat-sealable polyolefin -- is readily produced and yields an exceptionally strong and durable laminate useful inter alia for the production of container bags and pouches capable of retaining contents of substantial volume and/or weight.
