Abstract

A stack of hygiene sheet products including first and second webs that are interfolded with each other. The stack includes a top panel of the first web and a top panel of the second web, wherein the top panel of the first web overlays the top panel of the second web but has been cut away so that the top panel of the second web is revealed by the top panel of the first web. An adherence layer is placed on the top panel of the first web and the top panel of the second web and is exposed at the top of the stack so that it can adhere to an adjacent stack so that when the last sheets of the adjacent stack are pulled through a dispenser opening of a dispenser, the first and second sheets are pulled securely through with it as a result of the direct adherence.
