Abstract:
A sheet material dispensing system comprising:a dispenser defining an interior and an outlet for allowing sheet material to be dispensed from the interior of the dispenser; andsheet material in the interior of the dispenser, the sheet material comprisingwet formed sheet material having opposite side edges spaced apart from one another to define the overall width of the sheet material, andzones of weakness spaced along the sheet material, the zones of weakness comprising a plurality of perforations and frangible sheet material portions,wherein each of the zones of weakness has a strength equivalent to that of a perforated tear line having a total width of the frangible sheet material portions of from about 10% to about 30% of the overall width of the sheet material,wherein the sheet material has an elasticity in a dispensing direction of the sheet material of from about 4% to about 20%,wherein the sheet material has a dry tensile strength in the dispensing direction of from about 4,000 grams per 3 inches of width to about 12,000 grams per 3 inches of width, such that the sum of the tensioning forces exerted on the sheet material when pulled by a user exceeds the strength of the material as the zones of weakness pass over an edge of the outlet, andwherein the sheet material has a wet tensile strength in the weakest direction of at least about 900 grams per 3 inches of width.
