Abstract: A product comprising a stack of interfolded absorbent sheet materials. Each sheet is folded about a first and a second traverse fold axis into three consecutive segments. The middle segment of each sheet has the same dimension. Each sheet has the end segments positioned on the opposite sides of the middle segments forming a Z-shape cross-sectionally. Each sheet has the sum of the lengths of the end segments less than or substantially equal to the length of the middle segment. The middle segment of each sheet overlaps with the first end segment of its immediate succeeding sheet. The second end segment of each sheet overlaps with the middle segment of its immediate succeeding sheet. The second traverse fold axis of each sheet completely overlaps with the first traverse fold axis of the immediate succeeding sheet.
