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 personal hygiene article includes a chassis with a topsheet, a backsheet, and an absorbent component between the topsheet and the backsheet. At least one portion of the personal hygiene article includes a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region. The microporous film can include a beta-nucleating agent or can have thermally induced phase separation caused by a diluent. A container includes a microporous film enclosing at least one personal hygiene article. The microporous film has an opaque, microporous region and at least one see-through region of lower porosity forming a window within the opaque, microporous region. Methods of making the personal hygiene article and container are also described.
