Abstract:
A roll comprising a sheet of multi-ply, adhesively bonded, unembossed tissue product wound around a core, wherein the multi-ply tissue product comprises: i) n plies of tissue bonded to form said multi-ply sheet of said product wound around said core, each of said plies containing y square feet, and ii) adhesive, wherein said adhesive forms n-1 ply bonds between said n plies of tissue, said tissue product being further characterized in that:a) each of said ply bonds extends substantially across the entire width of the product and to within at least 3/4 inch of the core;b) said adhesive is applied between at least two of said plies and may optionally migrate to another of said plies in said multi-ply sheet, but said adhesive is applied such that it substantially does not migrate from one multi-ply winding of said sheet to an adjacent multi-ply winding of said sheet;c) the product's dry weight of adhesive is less than 25 pounds per million square feet of tissue ply bond, where the number of square feet of tissue ply bond =y*(n-1) and the dry weight of adhesive is sufficient to provide a median adhesive bond strength of at least 400 mg/cm; andd) each ply in the product is tissue.
