Abstract
An elastic-powered shrink laminate includes a shrinkable layer and an elastic layer bonded together while the elastic layer is in a dimensionally unstable, stretched state. The elastic layer remains substantially in the stretched state prior to shrinkage of the shrinkable layer. When the shrinkable layer is activated, the laminate retracts, and the retraction is aided (i.e. powered) by the elastic layer. The elastic-powered shrink laminate is useful in personal care absorbent articles where latent, post-assembly retraction of a waistband region is desired.
