Abstract

A three-dimensional substrate has a first surface, a second surface, land areas and comprises three-dimensional protrusions extending outward from the second surface of the three-dimensional substrate. The three-dimensional protrusions are surrounded by the land areas. The three-dimensional substrate is a laminate comprising at least two layers in a face to face relationship. The second layer comprise a tissue layer facing outward from the second surface of the three-dimensional substrate. The tissue layer comprises at least 80% pulp fibers by weight of the tissue layer.
