CLOSURE MEMBER FOR A RECLOSABLE THERMOPLASTIC BAG

摘要

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 i s 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 closur e member wherein a closure member profile is extruded and indentions are formed within and along the profile.
