Abstract

A closure member for a reclosable thermoplastic bag having opposing profiles wherein a first profile has an longitudinally extending part interlockable and substantially free of interdigitation with a second opposing profile and wherein the part is deformed defining indentions in the part to provide structural discontinuity along its length. The indentions form a raised portion intermittently along the longitudinal length of the profile such that the palmograph value of the closure member is increased while the closing force of the closure member is decreased. When the profiles are interlocked, an audible clicking sound and/or a vibratory or bumpy feel perceptible to the touch is imparted. Further disclosed is a process and apparatus for making the closure member wherein a closure member profile is extruded and indentions are formed within and along the profile.
