Method of making a mechanical fastening strip and reticulated mechanical fastening strip therefrom

A reticulated mechanical fastening strip having a longitudinal direction and a width direction, the reticulated mechanical fastening strip comprising:

• multiple strands of a thermoplastic backing attached to each other at bridging regions in the thermoplastic backing and separated from each other between the bridging regions to provide openings in the reticulated mechanical fastening strip, each of the multiple strands having a longitudinal dimension, which is the longest dimension of each of the multiple strands, a width dimension, and a thickness;
• and
• a plurality of upstanding posts on each of the multiple strands, the upstanding posts having bases attached to the thermoplastic backing and having caps distal from the thermoplastic backing, wherein the width dimension of each of the multiple strands is wider than at least the bases of the upstanding posts,
• wherein the plurality of upstanding posts on a first strand are arranged in a series that is non-parallel to a series of upstanding posts on a second, adjacent strand, and wherein both the plurality of upstanding posts and the multiple strands undulate along the longitudinal direction of the reticulated mechanical fastening strip.
