Abstract
A reclosable bag comprises a pair of opposing wall panels, a reclosable seal, and an optional tamper-evident partition.

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.
