ABSTRACT:
A form fit disposable diaper has an absorbent pad folded intermediate the ends to provide increased absorbent material in the crotch and has water impervious side seal strips folded over the pad in the crotch to minimize leakage along the edges of the diaper and to prevent the absorbent pad from shifting. A quantity of water absorbent polymer is employed to enhance moisture absorbing capabilities. The side seal strips are desirably perforated to permit moisture strike through into the pad but prevent transfer of the polymer to the facing sheet and the skin of the diaper wearer.
