Abstract: A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.

Abstract: A reclosable package and processes for making it are disclosed. The reclosable package includes a front panel, a back panel, an upper seal region adapted to be broken to allow a first opening of the reclosable package, a lower seal opposite the upper seal region, a vertical seal extending between the upper seal region and the lower seal on the back panel between the first side edge and the opposing second side edge; and a self-mating fastener disposed adjacent the upper seal region in an interior of the reclosable package. The self-mating fastener includes first and second fastener members each having fastener elements, an open configuration to allow access to the interior volume of the reclosable package, and a closed configuration in which the fastener elements of the first and second fastener members are engaged. In the closed configuration, the self-mating fastener is up to 800 micrometers thick.
