Abstract

A reclosable packaging having a slider/zipper assembly, a header and a tamper-evident feature which undergoes a tangible change when the slider is moved relative to the header for the first time. The tamper-evident feature comprises a layer of sticky or adhesive material placed between a surface of the header and an opposing surface of the slider, thus forming a seal. The material must have a peel strength or resistance to rupture sufficient to resist an initial movement of the slider along the zipper. If the slider is stuck or adhered to the header, this indicates that the package or bag has not been tampered with, i.e., previously opened. When sufficient force is applied, the seal can be broken, allowing the slider to move relative to the header along the zipper in the direction of opening. Once broken, the seal cannot be restored by simply returning the slider to its original position and pressing the slider against the sticky or adhesive material. Thus the slider remains in an unsealed state which is readily detectable by the consumer, thereby providing a tangible indication that the package has been previously opened.
