ABSTRACT:
A method of providing a convoluted area on a first thermoplastic elastomeric film, by applying to the film, one or more discrete pieces of a second thermoplastic elastomeric film, wherein the second film is differentially expandable as compared to the underlying first film. The differential expansion may be caused by application of an agent which causes the second film to swell. Products made according to this method may have elongated strips or other shapes of the second film bonded to the first film in areas of the product for which convolutions, puckers or other regular or irregular deformations are desired.
