    摘要: An elastomeric composite web (20) includes an elastomeric-substrate (22), and an operative layer of an elastomeric polypropylene-based adhesive material (24) or other surface modifying agent which is adhered or otherwise applied directly to at least one major, facing-side (26) of the elastomeric-substrate (22). In particular aspects, the layer of the surface modifying agent (24) has been provided separate from the elastomeric-substrate (22), and the layer of surface modifying agent (24) has been applied directly to the elastomeric-substrate (22) while the elastomeric-substrate has been operatively configured in a substantially unstretched condition. In other aspects, the elastomeric-substrate (22) can have a distinctively high basis weight, and the layer of surface modifying agent (24) can be applied directly to the elastomeric-substrate (22) prior to attaching the elastomeric-substrate to any separately provided, substantially non-elastomeric, supplemental-substrate. In a further aspect, the elastomeric-substrate (22) can be substantially free of continuous, elastomeric strands.

    摘要: Absorbent articles having form fitting properties are disclosed. In particular, the absorbent articles include at least one waist elastic member that extends a substantial distance in the longitudinal direction. The waist elastic member, for instance, may be positioned in a front region of the article, in a back region of the article or in both the front and back regions. The waist elastic member comprises a breathable elastic film. In order for the film to be breathable, the film includes apertures. The apertures appear on the film according to a particular pattern and having a particular diameter so that the film retains desired stretch properties.

    摘要: An adhesive composition including an atactic polymer, an isotactic polymer, and an extensible base polymer, such as ethylene-vinyl acetate and/or ethylene methacrylate. The composition may also include a tackifier, such as a high softening point tackifier resin, a low softening point additive, and/or other additives, such as an antioxidizing agent, a plasticizer, mineral oil, color pigment, filler, polymer compatibilizer, or a combination of any of these additives. Facing layers, particularly stretchable and/or elastomeric substrates, can be bonded with the adhesive composition. The adhesive composition maintains high bond strength, even at body temperature and after initial stretching. Such adhesive compositions and laminates can be made according to a method of the invention.
