An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer; and the multi-layer coextruded elastomeric film may have a basis weight no greater than about 40 gsm.

Extrusion bonded laminates for absorbent articles

An absorbent article comprising a topsheet, an outer cover, at least one chassis component, and an absorbent core disposed between the topsheet and outer cover, wherein at least one of the outer cover or chassis component comprises a laminate comprising at least one nonwoven layer and at least one multilayer film, wherein the multilayer film has at least four layers and comprises at least one inner layer comprising one or more elastomeric components, at least one outer layer comprising a plastoelastic component, and at least one additional polymeric layer that is disposed next to an inner layer.

Absorbent articles with multilayer laminates

An absorbent article comprising a topsheet, an outer cover, at least one chassis component, and an absorbent core disposed between the topsheet and the outer cover, wherein at least one of the outer cover or chassis component comprises a dual bilaminate comprising two bilaminates combined, wherein each bilaminate comprises at least one nonwoven layer and at least one multilayer film, and wherein the dual bilaminate has at most about 90 grams per square meter basis weight.

Absorbent articles with multilayer dual laminates

An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer. And, the first outer layer may comprise an amount of draw down polymer greater than about 45 wt %.

Diapers, including infant diapers, training pants, and adult incontinence articles, and the like having a specific elastically stretchable transverse separator sheet for excrement separation and/or isolation away from the skin, and process for making the same.

Diaper with separator sheet

Absorbent articles in which the outer cover has an extrusion bonded laminate.

Embodiments of the present disclosure may provide various properties of slow recovery polymers, films, and laminates that in combination with an hydrogenated block copolymer provide for (1) an order-disorder transition temperature of greater than about 135&#xb0; C., (2) a hard phase glass transition temperature of greater than about 60&#xb0; C., (3) a combination of one or more hard block associating ingredients that maintain or increase the glass transition temperature of at least one equivalent hard block polymer of the hydrogenated block copolymer, (4) a force retention factor of greater than about 2, (5) aromatic substitution of either or both the soft block and the hard block, (6) hard blocks with a solubility parameter of greater than about 9.1 (cal/cm), and (7) compositions that remain extendable to at least 50% engineering strain after exposure to isopropyl palmitate for 30 hours at room temperature.

Elastomeric compositions that resist force loss and disintegration

An absorbent article may comprise a topsheet, a backsheet joined with the topsheet, an absorbent core interposed between the topsheet and backsheet; and a slow recovery stretch laminate. The slow recovery stretch laminate may be joined to one or more article elements selected from the group consisting of the topsheet, the backsheet, the core, an anal cuff, an elasticized topsheet, a fastening system, a leg cuff, a waist elastic feature, a side panel, an ear, and combinations thereof. The slow recovery stretch laminate may exhibit an unload force at 37&#xb0; C. of about 0.16 N/(g/m) or greater and a percent of initial strain after 15 seconds of recovery at 22&#xb0; C. of about 10% or greater. And, the slow recovery stretch laminate may comprise an elastic member that was pretreated prior to and/or during draw down of the elastic member.
