Laminate webs and absorbent articles having the same
A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements such as recesses, protrusions, apertures, embossing and combinations thereof.
1. A laminate web comprising a polymer film layer comprising polymer film, a nonwoven layer comprising a nonwoven web, a first side comprising the polymer film, and a second side opposed to the first side, the second side comprising the nonwoven web, wherein the laminate web further comprises:
a) an array of first elements extending from the polymer film, wherein the array of first elements comprises apertures, wherein the array of first elements comprises a first plurality of first elements, a second plurality of first elements, and a third plurality of first elements,
b) a plurality of second elements formed downwardly from the first side of the laminate web, each of the plurality of second elements being longitudinally and laterally spaced from one another, wherein the second elements are recesses, and
c) a land area defined between and surrounding the plurality of second elements, the land area comprising the first plurality of first elements, and the land area being disposed in a first region of the laminate web,
wherein the recesses extend below the second side of the laminate web in the first region, so that a bottom area of each of the recesses is below the second side of the laminate web comprising the land area, wherein each of the recesses comprises a sloped side wall extending to a distal portion that at least partially defines the bottom area, wherein the sloped side wall comprises the second plurality of first elements and the distal portion comprises the third plurality of first elements,
wherein the first plurality of first elements has a greater number of first elements than the second plurality of first elements,
wherein at least one of the first elements in the third plurality of first elements is larger than at least one of the first elements in the second plurality of first elements, and
wherein at least one first element in each of the recesses has an open distal end larger than at least one of the open distal ends of the first elements in an adjacent portion of the land area, wherein the open distal end of the at least one first element in at least some of the recesses is at least two times larger.
2. The laminate web according to claim 1 , wherein the bottom area each of the recesses is at least about 50 um below the second side of the laminate web.
3. The laminate web according to claim 1 , wherein the bottom area is from about 0.05 mm 2 to about 15 mm 2 .
4. The laminate web according to claim 1 , wherein the first elements are extending upwardly away from the nonwoven layer.
5. The laminate web according to claim 1 , wherein each of the recesses has a shape in a plan view selected from the group consisting of a circle, oval, quadrilateral shape, hexagonal shape, octagonal, and combinations thereof.
6. The laminate web according to claim 1 , wherein each of the recesses has a lozenge shape in a plan view.
7. The laminate web according to claim 1 , wherein the laminate web further comprises a plurality of third elements selected from the group consisting of apertures different from the apertures of the first elements, embossments different from the recesses of the second elements, and a combination thereof.
8. The laminate web according to claim 1 , wherein the polymer film layer has higher stretchability than the nonwoven layer.
9. The laminate web according to claim 1 , wherein the laminate web comprises the recesses with a recess density of from about 10 to about 50 recesses/cm 2 web.
10. An absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the topsheet comprises the laminate web according to claim 1 .
11. The absorbent article according to claim 10 , wherein the polymer film layer of the laminate web is an outer most layer in the absorbent article facing the skin of a wearer.
12. The absorbent article according to claim 10 , wherein the nonwoven layer of the laminate web is an outer most layer in the absorbent article facing the skin of a wearer.
