Abstract
A laminated structure composed of a substrate web and a thermoplastic resin web extrusion-coated thereon, which is substantially free from an offensive odor, is produced by extrusion-coating the thermoplastic resin web in the molten state through a T-die on the substrate while applying an oxidizing gas to one surface of the as-extruded molten web of the thermoplastic resin and an inert gas to its other surface in a specified space.
