Abstract: The invention includes a hot melt adhesive composition based on polyolefin polymers that can be used for construction applications in a disposable absorbent article. The olefin based hot melt adhesive composition has surprisingly good cohesive strength and a low odor.
Abstract: Methods, articles, and apparatus that provide a dual function closure/opening system that utilizes a tape serving as both a sealing closure and as an opening mechanism. For example, in one embodiment, a single adhesive tape is introduced between a container flap and a container panel and then the container flap and the container panel are pressed together forming a bond between the flap and the panel via the adhesive tape thereby closing the container. In another embodiment, one end of a container includes two overlapping flaps and a single adhesive tape is introduced between the overlap of the two container flaps and then the container flaps are pressed together forming a bond between the flaps via the adhesive tape thereby closing the container. The methods and apparatus disclosed herein are directed to any container with at least one flap that overlaps a side panel of the container or that overlaps another flap.

Abstract: This invention claims hot melt adhesive compositions that can be used to form elastic composites that are useful in disposable absorbent articles. The compositions have good elastic recovery and high peel adhesion at a viscosity of less than about 20,000 cps at 177° C. The low viscosity makes it possible to apply the adhesive at a high line speed and target application to only those areas requiring elastic performance.

Abstract: The invention features a hot melt adhesive composition based on olefin polymers that can be used for elastic attachment in the manufacture of a disposable article. The hot melt adhesive includes from about 3 to about 10% by weight of a first propylene-based copolymer having a melt index measured by ASTM D1238 (190° C., 2.16 kg) of no greater than about 5, a second propylene-based polymer with a viscosity at 190° C. of no greater than about 5000 cps, a first tackifying agent having a softening point of at least about 90° C. and from about 5% by weight to about 20% by weight of a plasticizer.
Abstract: The inventors have discovered that certain hot melt adhesives can be used to form a stable stacked pallet that can limit the need for additional packaging materials e.g. inter-layer and pallet wrap.
Abstract: The invention features a hot melt adhesive composition that can be applied at temperatures as low as 107° C., while maintaining excellent bonding under stress and a very fast setting time.
