Abstract

A flexible, bag-like package which includes an access opening containing a reclosable seal at or near its top edge, is encompassed by a tamper-evident band. The band is bonded to the front and back wall panels of the package and extends across the access opening. Attempts to remove the band in order to open the package will result in disruption of the band or the wall panels.
