Formed film laminate for absorbent articles
A formed film laminate includes two formed films. Each formed film includes a first side and a second side. The first side includes a plurality of elongated ridges extending from a first land area, a plurality of valleys defined by adjacent elongated ridges and the first land area, and a plurality of primary apertures located at bottoms of the valleys. The second side includes a plurality of apertured protuberances extending from a second land area. Each of the protuberances includes a continuous sidewall extending to a distal end that includes a secondary aperture substantially aligned with a primary aperture. The first and second formed films have a thickness greater than about 0.9 mm under a pressure of 0.071 psi. The first formed film and the second formed film are rotationally offset by an angle greater than 0° and less than or equal to 90°.

wherein the first peaks are spaced from the first land area by a first distance that is uniform from a first end to a second end in the first direction; and
a second formed film comprising
a third side comprising
a plurality of second protrusions in the form of second elongated ridges having second peaks extending from a third land area of the third side and oriented in the first direction,
a plurality of second valleys defined by adjacent second protrusions and the third land area and oriented in the first direction, and
a plurality of second primary apertures located at bottoms of the second valleys; and
a fourth side opposite the third side, the fourth side comprising
a plurality of second apertured protuberances, each of the second apertured protuberances comprising a second continuous sidewall extending from a fourth land area of the fourth side to a second distal end comprising a second secondary aperture, wherein each second secondary aperture is substantially aligned with a second primary aperture,
wherein the second formed film has a thickness greater than about 0.9 mm under a pressure of 0.071 psi, and a thickness greater than about 0.3 mm under a pressure of 0.6 psi,
wherein the plurality of second protrusions excludes the plurality of second primary apertures and the plurality of second apertured protuberances,
wherein the plurality of second protrusions are narrower than the plurality of second valleys, and
wherein the second peaks are spaced from the third land area by a third distance that is uniform from a third end to a fourth end in the first direction;
wherein the first formed film and the second formed film are rotationally offset by an angle greater than 0° and less than or equal to 90°.
