Disposable absorbent articles assembled from a collection of components using an adhesive consisting essentially of an amorphous polyolefin composition comprising more than 40% 1-butene and a second amorphous polymer comprising at least one butene monomer, the polymer having a molecular weight (MW.sub.n) of at least 1000, wherein the polymer is compatible with the polyolefin.

Described herein is an absorbent article including (a) an absorbent core, a first nonwoven material, a second nonwoven material, and a bond area; and (b) a polymeric filler composition disposed within the bond area. The polymeric filler composition has less than 1% of a tackifier. The polymeric filler composition is chosen from a propylene butene copolymer, a polypropylene homopolymer, a propylene ethylene copolymer, and mixtures thereof. The polymeric filler composition has a Tensile Strength at Yield of from about 0.5 MPa to about 10 MPa. The bond area has a Peak Peel Strength of from about 0.1 N/cm to about 9 N/cm after exposure to a skin-protecting material for 24 hours.

An absorbent article comprising a first nonwoven material joined to a second nonwoven material by at least one bond area, wherein a polymeric filler composition is disposed within the bond area and the composition comprises at least one polymer selected from the group consisting of polypropylene homopolymers, propylene-ethylene copolymers, and mixtures thereof, wherein the composition is substantially free of tackifiers. It was found that such polymer filler compositions having a Toughness of at least 25 MPa, as measured according to the Extensional Test Method described herein, provide bonds with good resistance to peel creep force.

Disposable absorbent articles assembled from a collection of components using an adhesive composition is disclosed. The adhesive composition comprises at least 90 wt. % of a copolymer, wherein the copolymer comprises from about 30 mole % to about 70 mole % of propene monomer units and from about 30 mole % to about 75 mole % of 1-butene monomer units. The adhesive composition is free of a heterophase copolymer.

A hygiene product is provided having a waterproof layer with a perimeter and an adhesive strip disposed around the perimeter of the waterproof layer. The adhesive strip has a body-facing side and an air-facing side, wherein the body-facing side has an adhesive material that is configured to adhere to a user's body and the air-facing side has an adhesive material that is configured to adhere to the perimeter of the waterproof layer. The hygiene product also includes a pull tab attached to the waterproof layer, wherein the pull tab is configured to detach at least a portion of the waterproof layer from the adhesive strip to define an opening through the adhesive strip and the waterproof layer is re-attachable to the adhesive strip after the at least a portion of the waterproof layer is detached from the adhesive strip.

Absorbent articles with front and rear opening features are disclosed. An article may comprise an insert comprising an outer cover, a liner, and a core between the outer cover and liner, a first waist panel coupled to the insert throughout a first attachment region, and a second waist panel coupled to the insert throughout a second attachment region, the second panel being coupled to the first panel proximate a first side edge of the article and the second side edge of the article and further comprising a weakened region. The second attachment may comprise a low-strength attachment zone and a high-strength attachment zone, the high-strength attachment zone disposed proximate the attachment region bottom edge. The low-strength attachment zone may further have a first peel strength and the high-strength attachment zone may have a second peel strength, the second peel strength greater than the first.

A disposable absorbent article having a longitudinal centerline and a lateral centerline generally perpendicular to the longitudinal centerline is described herein. The disposable absorbent article has a topsheet; a backsheet; and an absorbent system disposed between the topsheet and the backsheet. The absorbent system has a first and second absorbent core configured such that there is an overlap between the first and second absorbent core and a pair of outboard distances for the first and second absorbent cores.

Disposable absorbent articles are disclosed herein having a first and second fold line. The disposable absorbent articles have a topsheet, a backsheet, and an absorbent system disposed therebetween. The absorbent system has a first absorbent core and a second absorbent core which may be configured in an offset manner. And, the absorbent system and/or the first and second fold lines may be configured with respect to the absorbent article to effect a caliper change in the folded article.

A hot melt adhesive material and articles made using the hot melt adhesive to assemble structures in an article. The adhesive material typically is manufactured by blending amorphous polymer with a compatible amorphous polymer.

Absorbent articles with front and rear opening features are disclosed. An article may comprise an insert comprising an outer cover, a liner, and a core between the outer cover and liner, a first waist panel coupled to the insert throughout a first attachment region, and a second waist panel coupled to the insert throughout a second attachment region, the second panel being coupled to the first panel proximate a first side edge of the article and the second side edge of the article and further comprising a weakened region. The second attachment may comprise a low-strength attachment zone and a high-strength attachment zone, the high-strength attachment zone disposed proximate the attachment region bottom edge. The low-strength attachment zone may further have a first peel strength and the high-strength attachment zone may have a second peel strength, the second peel strength greater than the first.
