Abstract
Reclosable bags having a slider-actuated string zipper and a tamper-evident feature. In one aspect, the reclosable bag comprises: a receptacle having a mouth and an interior volume; a string zipper installed in the mouth; a slider mounted to the string zipper; and a tamper-evident feature that blocks access to all or a portion of the interior volume. The tamper-evident feature may take the form of an internal membrane that partitions the interior volume or an external header that covers the string zipper. In some embodiments with a partitioned interior volume, the tamper-evident feature comprises a peel seal.
