Disposable absorbent article having absorbent core exhibiting planar growth when wet

A disposable absorbent comprising:

• a chassis comprising a bodyside liner, an outer cover, and an absorbent core sandwiched between the liner and the outer cover, the absorbent core defining a longitudinal direction, a transverse direction, an absorbent core perimeter, and an absorbent core area;
• wherein the absorbent core exhibits planar growth of at least 15% in at least one of the longitudinal and transverse directions at at least one measurement position when the absorbent core is tested in accordance with the Modified In-Product Planar Growth Test;
• wherein the bodyside liner and the outer cover each extend beyond the absorbent core perimeter to define a chassis peripheral area,
• wherein the bodyside liner and the outer cover are unconnected to each other within a portion of the chassis peripheral area to define an open area, and are connected to each other within at least a portion of the chassis peripheral area to define a sealed area,
• wherein the open area is at least about 5% that of the absorbent core area.
