The specification discloses a method for extrusion coating multiple substrate webs on a dual or tandem extruder system having multiple extruder stations. The method includes as an initial step providing a first substrate web and a second substrate web wherein each of the first and second substrate webs has a coating side and an underside. The webs are temporarily joined to form a composite web wherein the respective coating sides face outward and the respective undersides face one another. A first polymer coating is extruded on the coating side of the first web at a first extrusion station. Subsequently, a second polymer coating is extruded on the coating side of the second web at a second extrusion station. The extrusion coated first and second webs are then separated. The invention enables more efficient and economical use of dual or tandem extruder systems.
