Abstract

Claims (35)

1. An absorbent article comprising: a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and at least one elastically elongatable panel joined to the chassis, wherein the elastically elongatable panel comprises an ultrasonically bonded stretch laminate comprising:

a first nonwoven and a second nonwoven; and

an elastomeric film sandwiched between the first and second nonwovens, wherein the elastomeric film has two surfaces and a skin on at least one of the surfaces;

wherein the laminate comprises a zone that is unactivated,

wherein the elastomeric film comprises activation stripes, and

wherein a portion of the laminate is elastically extensible in a stretch direction.

2. The absorbent article of claim 1 , wherein the skin comprises polyolefin.

3. The absorbent article of claim 2 , wherein the skin comprise polyethylene.

4. The absorbent article of claim 1 , wherein the film comprises elastically extensible materials selected from the group comprising: styrene-isoprene-styrene block copolymers, styrene-butadiene-styrene block copolymers, styrene-ethylene-butylene-styrene block copolymers, polyurethanes, ethylene copolymers, polyether block amides, and combinations thereof.

5. The absorbent article of claim 1 , comprising a fastener joined to the elastically elongatable panel, wherein the elastomeric film is in partial overlapping relationship with the fastener.

6. The absorbent article of claim 5 , wherein the elastically elongatable panel is joined to the fastener in at least in a portion of the zone that is unactivated.

7. The absorbent article of claim 1 , wherein the elastomeric film is between about 20 μm and about 60 μm thick.

8. The absorbent article of claim 7 , wherein the elastomeric film is about 50 μm thick.

9. The absorbent article of claim 1 , wherein the first nonwoven and/or the second nonwoven comprises a basis weight of about 30 gsm or less.

10. The absorbent article of claim 1 , wherein the first nonwoven and/or the second nonwoven comprises a spunbond layer and/or a meltblown layer.

11. The absorbent article of claim 1 , wherein the first nonwoven is directly bonded to the second nonwoven.

12. An absorbent article comprising: a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and at least one elastically elongatable panel joined to the chassis, wherein the elastically elongatable panel comprises an ultrasonically bonded stretch laminate comprising:

a first nonwoven and a second nonwoven; and

an elastomeric film sandwiched between the first and second nonwovens, wherein the elastomeric film has two surfaces and a skin on at least one of the surfaces,

wherein a portion of the laminate is elastically extensible in a stretch direction,

wherein a zone of the laminate is unactivated, and

wherein at least a portion of the skin of the elastomeric film is located in the zone and wherein the portion of the skin has a plurality of wrinkles and the wrinkles have furrows.

13. The absorbent article of claim 12 , wherein the skin comprises polyolefin.

14. The absorbent article of claim 12 , wherein the film comprises elastically extensible materials selected from the group comprising: styrene-isoprene-styrene block copolymers, styrene-butadiene-styrene block copolymers, styrene-ethylene-butylene-styrene block copolymers, polyurethanes, ethylene copolymers, polyether block amides, and combinations thereof.

15. The absorbent article of claim 12 , comprising a fastener joined to the elastically elongatable panel wherein the elastomeric film is in at least partial overlapping relationship with the fastener.

16. The absorbent article of claim 15 , wherein the elastically elongatable panel is joined to the fastener in at least a portion of the zone.

17. The absorbent article of claim 12 , wherein the elastomeric film is between about 20 μm and about 60 μm thick.

18. The absorbent article of claim 12 , wherein the first nonwoven and/or the second nonwoven comprises a basis weight of about 30 gsm or less.

19. The absorbent article of claim 12 , wherein the first nonwoven and/or the second nonwoven comprises a spunbond layer and/or a meltblown layer.

20. An absorbent article comprising: a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and at least one elastically elongatable panel joined to the chassis, wherein the elastically elongatable panel comprises an ultrasonically bonded stretch laminate comprising:

a first nonwoven and a second nonwoven, wherein the first nonwoven and the second nonwoven are directly bonded; and

an elastomeric film sandwiched between the first and second nonwovens, wherein the elastomeric film has two surfaces and a skin on at least one of the surfaces,

wherein a first portion of the laminate is elastically extensible in a stretch direction,

wherein a second portion of the laminate is inelastic, and

wherein the elastomeric film comprises activation stripes.
