Zusammenfassung:	A method is provided for bonding an adhesive to a polyolefin foam, and preferably a non-crosslinked polyethylene foam. The foam is useful as a liquid-impervious backing in a disposable absorbent article, such as a panty liner, a sanitary napkin, a diaper, a adult incontinent garment, a training pant, and the like. The adhesive is applied to a substrate which is then brought into intimate contact with one side of the foam's surface. Optionally, heat and pressure may be applied to enhance bonding.
