Abstract
An elastic laminate having an expandable facing layer, e.g., a nonwoven web with off-axis perforations, and an elastic film layer is produced to provide a preferential direction of extendability and retraction in the laminate. The elastic laminate is particularly useful as a waist area panel in disposable pant-like garments.
