Claim Text:
1. A container for storing welding wire, said wire susceptible to the effects of moisture which degrades weld quality, comprising: an inner rigid or semi-rigid fibrous container wall having a plurality of connected sides which define an interior region for storing welding wire; an outer rigid or semi-rigid fibrous container wall having a plurality of connected sides; at least one middle rigid or semi-rigid fibrous container wall between said inner and outer walls; and, at least two layers on opposed sides of said middle container wall, at least one of said at least two layers integrally fashioned with the outer wall and conjoined therewith for substantially preventing moisture or moisture vapor from penetrating into said container by forming a moisture barrier or moisture vapor barrier with said middle and outer container walls, said at least two layers for substantially preventing moisture or moisture vapor being selected from the group consisting of a planar sheet of polymer and a planar sheet of metallic material; said at least two layers on opposed sides of said middle container wall reducing gas marking or worm tracking by reducing the amount of moisture or moisture vapor which ingresses through said container walls, thereby improving weld quality in comparison to a container without said at least two layers on opposed sides of said middle container wall.
