Abstract
The article includes a thermoplastic layer having opposing first and second side edges and a first surface bearing male fastening elements. The thermoplastic layer is plastically deformed and has a retardance profile having an average retardance along a line from the first edge to a location 500 micrometers from the first edge and a distance from the first edge where 75% of the average retardance is observed of at least 10 micrometers. In some cases, a distance between the first and second side edges is up to 50 millimeters. In some cases, the article is a fastening tab. The method includes providing a thermoplastic film having opposing first and second side edges, with a distance between the opposing side edges of up to 50 millimeters, and stretching the thermoplastic film to form the thermoplastic layer, which is plastically deformed. The first surface of the thermoplastic film bears male fastening elements.
