Tissue sheets, such as are useful for facial or bath tissue, can be embossed with a fine scale embossing pattern to increase bulk with a minimal loss in strength. The fine scale embossing pattern contains at least about 15 discrete intermeshing embossing elements per square centimeter (100 per square inch) and can enable the tissue manufacturer to produce premium quality tissues having adequate softness, bulk and strength from conventional tissue basesheets without layering or throughdrying equipment. Depending on the starting basesheet material, tissues having a unique balance of properties can be produced, especially for conventional wet-pressed basesheets.
A two-ply tissue product comprising two wet-pressed tissue sheets, said product having a bulk of about 9 cubic centimeters per gram or greater, a specific elastic modulus of about 3 kilometers or less and a geometric mean tensile strength of about 500 grams or greater per 3 inches sample width.
A soft wet-pressed tissue sheet having a bulk of about 6 cubic centimeters per gram or greater, a specific elastic modulus of about 4 kilometers or less, and a geometric mean tensile strength of about 500 grams or greater per 3 inches sample width.
A soft throughdried tissue sheet having a bulk of about 9 cubic centimeters per gram or greater, a specific elastic modulus of about 3 kilometers or less and a geometric mean tensile strength of about 500 grams or greater per 3 inches sample width.
