Abstract

Claims (39)

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, wherein the first nonwoven is hydroentangled:

an elastomeric film joined to the first nonwoven, wherein the elastomeric film comprises a first surface and a second surface, wherein at least one of the first surface and the second surface comprises a skin, and wherein the elastomeric film comprises activation stripes;

a second nonwoven, wherein the elastomeric film is positioned between the first nonwoven and the second nonwoven, and wherein the first nonwoven is directly bonded to the second nonwoven;

an anchoring zone; and

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

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

3. The absorbent article of claim 2 , wherein the skin comprises 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 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 at least in a portion of the anchoring zone.

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 1 , wherein the elastically elongatable panel is an elastic waist feature or a side panel.

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

10. 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 at least one of the first nonwoven and the second nonwoven is hydroentangled, and wherein the first nonwoven is directly bonded to the second nonwoven; and

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

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

wherein a zone of the laminate is unactivated, and

wherein at least a portion of the skin of the elastomeric film comprises activation stripes.

11. The absorbent article of claim 10 , wherein the skin comprises polyolefin.

12. The absorbent article of claim 10 , 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.

13. The absorbent article of claim 10 , comprising a fastener joined to elastically elongatable panel.

14. The absorbent article of claim 10 , wherein at least a portion of the skin comprise a plurality of wrinkles, and wherein the plurality of wrinkles have furrows.

15. The absorbent article of claim 10 , wherein the elastomeric film is between about 20 μm and about 60 μm thick.

16. The absorbent article of claim 10 , wherein at least one of the first nonwoven and the second nonwoven comprises a basis weight of about 30 gsm or less.

17. The absorbent article of claim 10 , wherein the elastically elongatable panel is an elastic waist feature or a side panel.

18. 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 at least one of the first nonwoven and the second nonwoven are hydroentangled, and wherein the first nonwoven is directly bonded to the second nonwoven; and

an elastomeric film sandwiched between the first and second nonwovens, wherein the elastomeric film comprising a first surface and a second surface, wherein at least one of the first surface and the second surface comprises a skin,

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

wherein a second portion of the laminate is inelastic, and

wherein the elastomeric film comprises activation stripes.
