Improved laminated paper products are disclosed in which different paper layers are adhesively secured together with hot melt adhesives. According to one aspect of the invention, the hot melt adhesive is provided on less than the entire surfaces being joined to define an adhesive coated portion which is of an area or size sufficient to adhesively secure the paper layers together and an uncoated section which is of an area or size sufficient to permit evaporation of water across the facing surfaces of the first and second paper layers. Such a laminated paper product is particularly useful in the manufacture of corrugated cardboard products in which a paper liner is adhesively secured to the crests of a corrugated medium with a water-based emulsion adhesive. In such corrugated products in which the disclosed laminated paper product is used as either the liner or the corrugated medium, the water is capable of evaporating through the laminated paper product. The laminated paper products may also comprise wire reinforced paper products in which a plurality of wires are interposed between the paper layers and adhesively bonded to at least one of the paper layers with the hot melt adhesive. Further, particular laminated paper products and methods of manufacturing same are disclosed.
