A disposable absorbent article of a brief or pull-up type incorporates a breathable laminate material composed of three layers. The laminate is an elastic material and may include non-elastic portions created by deactivating the material. The laminate material may be made breathable by the ultrasonic bonding process used to create the laminate. The absorbent article includes an absorbent assembly that overlaps with the non-elastic portions of the laminate.
1. An absorbent article, comprising: a breathable front laminate section defining a front end edge, a front crotch edge parallel to and longitudinally spaced from the front end edge, first and second transversely opposed side edges extending in a longitudinal direction, and first and second leg edge
1. An absorbent article, comprising: a breathable front laminate section defining a front end edge, a front crotch edge parallel to and longitudinally spaced from the front end edge, first and second transversely opposed side edges extending in a longitudinal direction, and first and second leg edges, the front laminate section comprising: a polymeric film,a first nonwoven layer,a second nonwoven layer attached to a second side of the polymeric film opposite the first nonwoven layer,a plurality of spaced apart ultrasonic bonding sites attaching the first nonwoven layer to a first side of the polymeric film and the second nonwoven layer to a second side of the polymeric film opposite the first nonwoven layer,a plurality of trailing tears in the polymeric film adjacent to the respective plurality of ultrasonic bonding sites, each trailing tear forming a through passage that provides for the passage of water vapor through the front laminate,a second plurality of through passages that provide for the passage of water vapor through the front laminate, each passage formed within the perimeter of one of the plurality of ultrasonic bonding sites,a front non-elastic portion adjacent to the front crotch edge, anda front elastic portion adjacent to the front end edge;a rear laminate section defining rear end edge, a rear crotch edge parallel to and longitudinally spaced from the rear end edge, first and second transversely opposed side edges extending in a longitudinal direction, and first and second leg edges, the rear laminate section comprising a rear non-elastic portion adjacent to the rear crotch edge and a rear elastic portion adjacent to the rear end edge; andan absorbent assembly extending longitudinally between the front crotch edge and the rear crotch edge, the absorbent assembly comprising a topsheet, a back sheet and an absorbent core positioned between the topsheet and backsheet. 2. The absorbent article of claim 1 wherein the polymeric film is an elastomeric film. 3. The absorbent article of claim 2 wherein the non-elastic portion of the front laminate is formed by deactivating a portion of the elastomeric film. 4. The absorbent article of claim 1 wherein the polymeric film is a block copolymer. 5. The absorbent article of claim 1 wherein the ultrasonic bonding sites comprise a mixture of material from the first nonwoven layer, the polymeric film and the second nonwoven layer such that the first nonwoven layer, the polymeric film and the second nonwoven layer are bonded together. 6. The absorbent article of claim 1 further comprising a third plurality of through passages comprising perforations formed by passing a perforating tool through the front laminate. 7. The absorbent article of claim 1 wherein the absorbent core overlaps with the front non-elastic portion and the rear non-elastic portion and does not overlap with the front elastic portion and the rear elastic portion. 8. The absorbent article of claim 1 further comprising a front leg elastic adhered to a surface of the front laminate section and extending parallel and adjacent to the first front leg edge for at least a portion of the length of the front leg elastic. 9. The absorbent article of claim 1 further comprising a rear leg elastic adhered to a surface of the rear laminate section and extending parallel and adjacent to the first rear leg edge for at least a portion of the length of the rear leg elastic. 10. The absorbent article of claim 9 further comprising a covering layer that is adhered to a surface of the rear laminate section and covers the rear leg elastic. 11. The absorbent article of-claim 8 further comprising a covering layer that is adhered to a surface of the front laminate section and covers the front leg elastic. 12. The absorbent article of claim 1 wherein the second nonwoven layer is attached to a second side of the polymeric film opposite the first nonwoven layer.
