Abstract
A disposable diaper can be fastened securely around a person and be refastenable when it has an adhesive patch on the faces of corners at the back of the diaper, each of which patches contacts an adhesive patch on the front of the diaper, which patches form bonds to each other that have strong resistance to shear forces, can easily be peeled apart after 2 hours at room temperature and do not adhere either to ordinary packaging materials or to nonadhesive surfaces of the diaper. All of the adhesive patches can be cut from a single adhesive tape that has a flexible backing, one face of which bears a layer of the peelable adhesive while the other layer bears a layer of an adhesive that forms a strong, permanent bond to the diaper.
