Tamper-evident recloseable packaging for products such as cookies and crackers allows consumers to know whether the product has been previously opened. A 2-ply material forms the resealable closure. A releasable adhesive on either the sealing panel or the film layer or both adheres the panel and film layer. The sealing panel releases by peeling it back and recloses when the sealing panel is moved back against the top. Advantageously, the transferable material’s coating is a different color or pattern than that of the film layer or sealing panel; thus, if the coating is initially applied to the sealing panel, it is evident whether the closure has been opened. If the perimeter edge of the sealing panel is nonlinear, such as a zigzag pattern, a slight misalignment of the zigzag pattern between the sealing panel and the film layer will be visible.
