Abstract
A flexible container with a wall structure comprised of multi-layer, flexible thin films, including a first film layer that is affixed to the wall structure by a releasable adherence and that incorporates a removable piece. The removable piece is incorporated into the first film layer such that, other than at least one continuous cut facilitating removal and any conspicuous printing on the removable portion, it is indistinguishable from the rest of the exterior of the package. The continuous cut allows for full or partial detachment of the removable portion from the first film layer so that only the releasable adherence prevents it from separating from the container. The removable piece is removed by peeling it away from the container, where the initiation of the peeling is facilitated by a smaller peel force adjacent the continuous cut. The removable piece may function as a promotional or collectible piece such as a gaming piece or redeemable coupon, or may be designed to retain a tacky surface and function as a sticker or as a piece of tape to close an opened bag. The removable piece can also expose a tacky surface on the container to permit closure of the opened bag.
