Abstract

A latent elastic film laminate is provided including a film predominantly comprising olefin elastomers. The film is stretched and maintained in a stretched state in order to impart the desired level of latent elasticity such that the conditioned film laminate will shrink upon activation, such as by heating. The latent elastic film laminate can be advantageously used in the manufacture of various elasticated articles, including absorbent personal care articles, by activating the latent elasticity after attachment to the article and thereby shirring and elasticizing components to which the film laminate is attached.
