Closure arrangements for recloseable pouches; recloseable pouches; and, methods

摘要

Reclosable zipper arrangements for bags such as thermoplastic bags are described. The reclosable zipper arrangements are configured to advantageously provide a clicking sensory indicator, in the form of a tactile and/or audible indication of sealing, as zipper closure occurs. Package arrangements using the closure arrangements are described. Also, methods of assembly and use are described.
