Abstract
A disposable pull-on garment is provided having a front region, a back region and a crotch region. The garment includes a chassis having edge lines in the front and back regions. A pair of extensible front ear panels extends laterally outward from the chassis in the front region, and a pair of extensible back ear panels extends laterally outward from the chassis in the back region. Each of the panels is joined along its outermost edge line to its corresponding opposite front or back ear panel to form two overlapping seams, two leg openings and a waist opening. At least one of the overlapping seams has a substantially bonded portion and an unbonded portion such that the ratio in the length of the unbonded portion to the substantially bonded portion is between about 4:96 and about 20:80.
