Abstract

Reclosable zippers for reclosable packages are disclosed. The zippers include male and female profiles. The female profiles are periodically inwardly and/or upwardly deformed in order to generate tactile and audible feedback when the zippers are opened or closed by the user. The deformation of the female profiles typically maintains the strength of the zipper.
