Abstract
An elastic laminate having fragrance releasing microcapsules embedded within a nonwoven web layer of the laminate is generally disclosed. The elastic laminate is configured to release the encapsulated fragrance upon stretching the laminate. The elastic laminate can continue to release fresh fragrance even after the first stretching force is applied, effectively extending the life of the elastic laminate. The resulting elastic laminate is useful for many applications, and is particularly useful in the construction of an absorbent article.
