Disposable insole pads and use thereof are disclosed. The disposable insole pads are multilayer structures comprising a topsheet and a pressure sensitive adhesive, and optionally a backsheet, silicone coating and liner layers. The pressure sensitive adhesive layer allows the disposable insole pads to be positioned, repositioned and removed, making them well suited for daily use and disposal.

Disposable insole pads and use thereof

The sprayable olefin-based hot melt adhesive and absorbent articles comprising the adhesive are disclosed. The sprayable olefin-based hot melt adhesive is particularly suitable for spraying at low application temperatures. The sprayable low application temperature hot melt adhesives have high green strength, excellent bond strength and aging performance. Moreover, the sprayable low application temperature hot melt adhesives allows for thin bond lines without bleed-through and burn-through risks for heat-sensitive substrates.

Hot melt adhesive composition and use thereof

Stretch laminate hot melt adhesives and stretch laminates are described. The stretch laminate hot melt adhesives are suitable for adhering elastic materials with inelastic substrates, and allow permanent deformation of the inelastic substrate and extensions and retractions of the elastic materials. The stretch laminate hot melt adhesive is particularly suitable for back ear lamination for disposable absorbent articles.

Stretch laminates

Propylene polymer based packaging films for encapsulating hot melt adhesives are disclosed. The packaging films are readily miscible with the various hot melt adhesive chemistries during the melting stage without deleteriously affecting the adhesive properties, making the packaging film particularly well suited for packaging hot melt adhesives in a pillow, cylinder, pouch, block, cartridge and like forms.

Integral hot melt adhesive packaging films and use thereof

The invention relates to a low application temperature hot melt adhesive. More specifically, the low application temperature hot melt adhesive comprises olefin copolymers with an average Melt Index greater than 5 but less than about 35 g/10 minutes at 190&#xb0; C. The adhesive is particularly useful in the construction of nonwoven articles.

Low application temperature hot melt adhesive

Adhesives, methods to bond substrates together with the adhesives, and articles of manufacture comprising the adhesives are described. It has been discovered that an adhesive with a polymer content greater than 70 weight percent can be formulated with a blend of (i) a metallocene catalyzed polypropylene polymer that has a density range of about 0.70 to about 0.91 g/cmand a melt viscosity less than 50,000 cP at 190&#xb0; C. and (ii) a Ziegler-Natta catalyzed amorphous polybutene and/or polypropylene copolymer. Such adhesives have high creep resistance making them particularly well suited for disposable personal care garments.

Adhesives and use thereof

It has been discovered that amorphous polybutene copolymers that have a softening point of from about 70 to about 105&#xb0; C. and viscosity of less than about 1,900 cP at 190&#xb0; C. possesses desirable properties and may be used to make a low application temperature hot melt adhesive for disposable absorbent articles.

Low application temperature amorphous poly-a-olefin adhesive

The present invention relates to a process for producing free-flowing, agglomeration resistant amorphous poly-alpha-olefin based adhesive pellets. The process includes (a) extruding the adhesive through an orifice of a die plate immersed in a cooling fluid; (b) cutting the adhesive into a plurality of pellets in the cooling fluid; (c) solidifying the pellets at a temperature range of about 25&#xb0; C. to about 40&#xb0; C. for at least 30 minutes; and (d) separating the pellets from the recrystallization fluid and drying the pellets. The pellets harden at least three folds faster than conventionally formed pellets.

Process for preparing flowable amorphous poly-alpha olefin adhesive pellets

The present invention is directed to adhesives suitable for application using a hot melt process at a relatively low temperature in the range of about 110&#xb0; C. to about 130&#xb0; C. Such adhesives exhibit desirable viscoelastic properties and are suitable for bonding an elastic attachment in the manufacture of disposable articles, such as disposable diapers.
