Abstract: A substantially rectangular disposable diaper having a longitudinal dimension defined between end margins and a shorter transverse dimension defined between side margins is prefolded and packaged in a unique configuration including a double-pleat fold on each side of the diaper. Each double-pleat fold includes an inner panel overlying a central section of the diaper and an outer panel overlying the inner panel. Each outer panel includes two wing sections; one on each side of a transversely extending medial line of the diaper. Therefore, the four wing sections of both outer panels are disposed in pairs of two; one pair being on each side of the transversely extending medial line. The two wing sections which are on the same side of the medial line diverge from each other in a direction from the medial line to an end margin of the diaper. The double-pleat folded diaper is folded along the transversely extending medial line to complete the prefolded configuration in which the diaper is packaged.
