ABSTRACT An article having a refastenable tape system comprising a flexible substrate having a tear strength, and an adhesive tape member having a peel adhesion value which is greater than the tear strength of the substrate when the tape member is adhered to a first major surface of the substrate. A reinforcement layer composed of a hot melt adhesive is bonded to a second major surface of the substrate located opposite to the first major surface. The reinforcement layer exhibits an elongation-at-break of at least about 100%. The substrate and the reinforcement layer thereby provide a composite tear strength greater than the peel adhesion value of the tape member, and provide a composite elongation-at-break of at least about 100%.
