ABSTRACT:
A reclosable bag comprises a pair of opposing wall panels, a reclosable seal, and an optional tamper-evident partition. The pair of opposing wall panels are joined along a pair of opposing sides and a bottom bridging the opposing sides to create a receptacle space having a mouth end opposite the bottom. The reclosable seal extends along the mouth end, and includes first and second opposing reclosable elements and first and second fins extending downward from the respective reclosable elements. The reclosable elements are releasably engageable to each other. The first and second fins are connected to the respective opposing wall panels. The tamper-evident partition is located below the reclosable elements and forms a one-time breakable preferential area of weakness. The tamper-evident partition separates an interior of the bag from a first area bounded in cross-section by the tamper-evident partition, the fins, and the engaged reclosable elements. The tamper-evident partition includes first vents positioned to allow air from the interior of the bag to escape into the first area. The fins include second vents allowing air from the first area to escape to a second area outside the bag. If the tamper-evident partition is not required, the first vents are eliminated, and the second vents may be located in either the fins or the wall panels and concealed to inhibit entry of bugs into the bag via the vents.
