Abstract
A laminated assembly extends in a longitudinal direction and a lateral direction orthogonal to the longitudinal direction, the assembly including a non-woven sheet and an elastic film that are laminated together, the non-woven sheet including at least one activated zone extending over the length of the non-woven sheet measured in the longitudinal direction and over a width that is strictly less than the width of the non-woven sheet measured in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction being different from the degree of activation of the elastic film in the lateral direction, the degree of activation of the activated zone of the non-woven sheet in the lateral direction lying in the range 20% to 200%.
