Abstract
A method for producing a stretch laminate includes forming an intermediate stretch laminate. Forming the intermediate stretch laminate includes providing a first substrate and attaching an elastic film to a surface of the first substrate via an adhesive. The first substrate and the elastic film are in a face to face orientation. The intermediate stretch laminate has a residual energy of greater than or equal to 50% at a predetermined applied strain. The method of forming the stretch laminate further includes mechanically activating the intermediate stretch laminate at a strain rate of at least 100 s−1.
