Abstract
A strip of material for the delivery of an oral care active is disclosed. The strip of material includes a structural elastic-like film backing layer including a strainable network having a first region and a second region formed of substantially the same material composition, the first region providing a first, elastic-like resistive force to an applied axial elongation, and the second region providing a second distinctive resistive force to further applied axial elongation, thereby providing at least two stages of resistive forces in use; and an oral care composition disposed on the film, the oral care composition including an oral care active.
