Disposable absorbent articles having co-elongation

An absorbent article comprises a lateral axis defining a front portion and a back portion in the absorbent article, a topsheet, and a backsheet. The absorbent article further comprises an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The backsheet comprises a first backsheet zone positioned at least partially in the front portion, and a second backsheet zone positioned in the back portion. The first and second backsheet zones differ from each other in at least one physical property. The physical property is basis weight, thickness, density, and/or tensile modulus. The second backsheet zone overlaps a portion of the absorbent core in the back portion. The second backsheet zone is not bonded to the absorbent core in the area of overlap.

ABSORBENT ARTICLE COMPRISING ELASTOMERIC STRIPS

The present invention discloses a disposable or wearable absorbent article (1) that includes one or more elastomeric strand(s) (14) and/or strip(s) (16) on/in the backsheet (12) layer, localized in the absorbent core (10) region. The absorbent article (1) is preferably a baby diaper, an incontinence diaper, a pant or a pull up garment. The article may have a topsheet (6), a backsheet (12) and absorbent core (10) disposed between the topsheet (6) and backsheet (12), and a pair of longitudinal side edges. Elastomeric strand(s) (14) and/or strip(s) (16) is attached in longitudinal axis of the backsheet (12) of the absorbent article (1) in stretched form, whereby backsheet takes a crinkled form when it is in relaxed state. The absorbent article (1) fits better on users buttocks without sagging when the article is being worn.
