Abstract: A technique for imparting latent elasticity to components of an absorbent article is provided. More specifically, a latent elastic film that contains a crosslinkable semi-crystalline polyolefin is initially incorporated into an absorbent article. The film is not highly elastic prior to crosslinking and is thus dimensionally stable. Consequently, the film need not be maintained in a mechanically stretched condition during attachment to other components of the absorbent article, which provides for greater freedom in the location and manner in which the components are attached together. Once incorporated into the absorbent article, the semi-crystalline polyolefin is crosslinked to form a three-dimensional network having elastic memory. The film may also be heat activated, either through crosslinking or an additional step, to cause the film to shrink and further improve its stretch characteristics.
