ABSTRACT:
An article, which includes a refastenable adhesive tape fastening system, comprises an adhesive tape tab which has a peel force value of at least about 11.7 N, and a substrate layer which is composed of a nonwoven synthetic polymer material. The substrate layer has a matte finish, and has a tensile load capacity which is substantially unable to prevent tearing thereof when the tape tab is peeled from adhesive contact with the substrate layer. A reinforcement layer has a first major surface bonded to the substrate layer, and has a second major surface which is appointed for adhesive bonding with the adhesive tape tab. The reinforcement layer also has a matte finish and a yield tensile strength of at least about 15 MPa. The reinforcement layer and substrate layer thereby form a composite, reinforced substrate having a composite tensile load capacity capable of withstanding the peeling removal of the adhesive tape tab substantially without tearing.
