The method of making a laminate (100) includes stretching a thermoplastic layer (102) so that it plastically deforms, relaxing the plastically deformed thermoplastic layer (102) to reduce its tensile strain, and subsequently laminating the thermoplastic layer (102) to a substrate (104) to make the laminate (100). The stretching, relaxing, and laminating are completed in-line. The thermoplastic layer has a first surface and a second surface opposite the first surface, with the first surface of the thermoplastic layer bearing a plurality of male fastening elements. The second surface of the thermoplastic layer (100) is laminated to the substrate (104).
