In the Adhesive Application of Back Ears, Front Ears and the Side Panel on diaper and incontinence products, the ear tabs or fasteners are glued to the diaper. They can be glued at one side, when attached over the topsheet, or at both sides as a reinforcement. When gluing both sides, the diaper holds the ears between the topsheet and the backsheet like a sandwich. For this application, slot is typically preferred, but sometimes because of possible process interference, one of the sides is glued with spray while the other is glued with a slot. The typical adhesive used for this application is a PSA generally called 'Elastics Adhesive,' known to have a strong cohesion ratio.
