Abstract

A stretch activated disposable article, such as a wipe or mitt, includes an upper material layer, and a lower material layer joined to the upper material layer such that a space is defined between the material layers. A functional element, for example a fluid composition, is stored in the space between the upper and lower material layers and becomes functional upon being exposed through the upper material layer with use of the article. The upper material layer includes a plurality of materially weakened positions along the surface thereof that are configured to part or separate upon stretching of the upper material layer to expose the functional element through the upper material layer.
