An absorbent article selected from a sanitary napkin, an incontinence pad and a pantyliner, comprising a topsheet layer a backsheet layer a fastening adhesive applied on the backsheet garment facing surface, wherein at least a portion of said fastening adhesive (PFA) is applied in a pattern and wherein said backsheet layer is a plastic film having a basis weight of less than 20 gsm.

Thin nanocomposite film for use in an absorbent article

A thin nanocomposite film for use in an absorbent article is provided. The film contains an ethylene polymer, a nanoclay having an organic surface treatment, and a compatibilizer that includes an olefin polymer containing an ethylenically unsaturated carboxylic acid monomer. The present inventors have discovered that through selective control over the particular type and concentration of the components used to form the film, as well as the manner in which it is formed, the modulus and tensile strength of the film can be significantly improved without having an adverse impact on its ductility.

BREATHABLE DIAPER BACKSHEET
20210251819 · 2021-08-19 ·

A breathable thermoplastic polymer film may be produced and adapted for use as a breathable diaper backsheet. The film may comprise a blend of LLDPE, mLLDPE and calcium carbonate, and may have improved tear strength and melt strength such that instances of tears or break offs during the machine direction orientation portion of the production process are significantly reduced or eliminated. In addition, the film may have sufficient tear strength to permit omission of CDI processing needed to strengthen weaker prior art films. In this regard, undesired streaking of colors or printed aspects of the film may be reduced or avoided completely.

An absorbent article for wearing about the lower torso of a wearer includes a first waist region having a first waist edge, a second waist region having a second waist edge, and a crotch region disposed between the first and second waist regions. The article further includes a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is joined to the chassis and disposed in one of the first waist region or the second waist region. The waist gasketing element has a top layer and a bottom layer, and first area, A1. The top layer is bonded to the bottom layer in a closure bond region by a closure bonding technique. The closure bond region has an aggregate closure bond area, BA, which is at least about 10% of the first area, A1.

Methods of forming front and back waist gasketing elements on an absorbent article are provided. The methods include the steps of providing a web of chassis material and waist gasketing elements, each having a first transverse edge, a second transverse edge, a top and bottom layer. The methods further include bonding the top and bottom layers in closure bond regions, and joining the waist gasketing elements to the chassis to form a strip of final articles. The methods include dividing the strip of final articles between the first and second transverse edges such that a cut separates two final articles, a leading article and a trailing article, wherein each cut is disposed within a closure bond region, forms a back waist edge of the leading article and a front waist edge of the trailing article; and forms an outboard lateral edge of a back waist gasketing element on the leading article and an outboard lateral edge of a front waist gasketing element on the trailing article.

Absorbent article having waist gasketing element

An absorbent article for wearing about the lower torso of a wearer includes a first waist region having a first waist edge, a second waist region having a second waist edge, and a crotch region disposed between the first and second waist regions. The article further includes a first longitudinal edge, a second longitudinal edge, and a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is joined to the chassis and disposed in one of the first waist region or the second waist region. The waist gasketing element has a top layer and a bottom layer, an inboard lateral edge and an outboard lateral edge, and first area, A1. The top layer is bonded to the bottom layer in a closure bond region by a closure bonding technique. The closure bond region has an aggregate closure bond area, BA, which is at least about 10% of the first area, A1.

Absorbent article having odor absorbing material

An absorbent article includes a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. The absorbent core contains superabsorbent polymer material and about 10% or less by weight of cellulosic fibers. The backsheet comprises a film comprising a plurality of micropores. The film comprises odor absorbing material disposed in one or more of the micropores.

ABSORBENT ARTICLE WITH IMPROVED CORE-TO-BACKSHEET ADHESIVE

An absorbent article for personal hygiene comprising: a topsheet, a backsheet, an absorbent core, the backsheet comprising a plastic film having a longitudinal tear strength measured in N/cm; the absorbent core being partially attached to the plastic film of the backsheet by a first glue wherein at least a continuous area of 10 mm in longitudinal direction and 25 mm in transversal direction of the bottom side of the core is unattached to the backsheet by the first glue or by any other means of attachment. In the first glue application area, the absorbent article has a core-to-backsheet peel strength measured in N/cm, such that the core-to-backsheet peel strength ranges from 10% to 40% of the longitudinal tear strength of the plastic film.

ABSORBENT ARTICLE COMPRISING ELASTOMERIC STRIPS

The present invention discloses a disposable or wearable absorbent article (1) that includes one or more elastomeric strand(s) (14) and/or strip(s) (16) on/in the backsheet (12) layer, localized in the absorbent core (10) region. The absorbent article (1) is preferably a baby diaper, an incontinence diaper, a pant or a pull up garment. The article may have a topsheet (6), a backsheet (12) and absorbent core (10) disposed between the topsheet (6) and backsheet (12), and a pair of longitudinal side edges. Elastomeric strand(s) (14) and/or strip(s) (16) is attached in longitudinal axis of the backsheet (12) of the absorbent article (1) in stretched form, whereby backsheet takes a crinkled form when it is in relaxed state. The absorbent article (1) fits better on users buttocks without sagging when the article is being worn.
