<p>A reclosable plastic bag comprises first and second opposing panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The bag is provided with a reclosable zipper (22) extending along a mouth formed opposite the sealed bottom (20). The zipper includes a male track with a male profile and a female track with a female profile. A slider (32) is slidably mounted to the zipper for movement between a closed position and an open position. The male and female profiles are engaged to each other while the slider is in the closed position. The male and female profiles are disengaged from each other in response to movement of the slider to the open position. To prevent tampering with the contents of the plastic bag prior to being initially opened, the slider is initially parked in the closed position at one end of the zipper, and upper edges of the male and female profiles are detachably connected to each other, except at the one end of the zipper supporting the parked slider. The slider cannot be moved from the closed position until a one-time tamper-evident feature (36, 38) is broken or, alternatively, movement of the slider from the closed position will break the tamper-evident feature.</p> |
