A plastic bag comprises opposing body panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. A reclosable zipper extending along a mouth portion formed opposite the sealed bottom of the plastic bag. The zipper is preferably free of graspable upper pull flanges in order to best accommodate a slider and inhibit operation of the zipper without the slider. The slider is mounted to the zipper for movement between a closed position and an open position. The zipper is closed while the slider is in the closed position. The zipper is opened in response to movement of the slider to the open position. To inhibit tampering with the contents of the bag, the bag includes a tamper-evident feature. In one set of embodiments, the tamper-evident feature initially maintains the slider in the closed position and allows the slider to move away from the closed position toward the open position in response to removing or breaking the tamper-evident feature. In another set of embodiments, the tamper-evident feature initially maintains a mouth portion of the plastic bag in a folded position and allows the mouth portion to be unfolded in response to removing or breaking the tamper-evident feature.

Tamper-evident reclosable bag

A carton for a bag stack comprises a bottom wall, opposing front and back walls, and opposing first and second side walls bridging the opposing front and back walls. The first side wall forms a first pair of detents in proximity to the respective front and back walls. The second side wall forms a second pair of detents in proximity to the respective front and back walls. The front and back walls each include a profiled upper edge forming a window adapted to accommodate a human hand and allow retrieval of the plastic bags within the carton via the window. The bag stack includes first sets of plastic bags and second sets of plastic bags interleaved (alternately-arranged) with each other. Each set of plastic bags may include one or more plastic bags. The first and second sets of plastic bags are oriented in opposite longitudinal directions. The thickened portions of the first sets of bags are adjacent to and extend across the width of the front wall, while the thickened portions of the second sets of bags are adjacent to and extend across the width of the back wall. The distance between the first and second side walls is such that the first and second pairs of detents inhibit inward sliding of the interleaved sets of plastic bags, thereby maintaining the orderliness of the stack.
