Abstract
The method of making a laminate () includes stretching a thermoplastic layer () so that it plastically deforms, relaxing the plastically deformed thermoplastic layer () to reduce its tensile strain, and subsequently laminating the thermoplastic layer () to a substrate () to make the laminate (). 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 () is laminated to the substrate ().
