A self-engaging touch fastener, separable by peeling, includes portions with a generally thin shell structure and a closely spaced array of bilaterally undercut generally convex protrusions which are directed by proximate oblique stem walls into an interlocking relationship with corresponding receptors when the portions are compressed. Touch fastening products have a non-grabbing non-abrasive texture and may be manufactured of thin plastic films or similar low cost materials using a simple die-cutting/forming method, thus providing a user friendly reliable and economic alternative to hook-and-loop and other presently available fastening systems for connecting flexible materials for applications including packaging, apparel, and disposable products. The device may be furnished as an independent product, as an integrally formed or molded segment of a primary product, or attached to rigid or flexible substrates. An apparatus and method for economically manufacturing such device is also provided.
