A web or film useful for fastener tapes for diapers consists of more than one layer and is characterized in that the outer layers, or at least one layer, are/is inelastic and the inner layer, or other layer, is elastic, and the film becomes substantially completely elastic, at least at one of its lengthwise portions, by manual stretching to cause yielding of the inelastic layer or layers. |
