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 promotional piece. The removable promotional piece is incorporated into the first film layer such that, other than a 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 detachment of the removable portion from the first film layer so that only the releasable adherence prevents it from separating from the container. The promotional piece is removed by peeling it away from the container, where the peeling is facilitated by the action of the continuous cut and releasable adherence. The removable piece may function as a gaming piece or redeemable coupon, or may be designed to retain a tacky surface and function as a sticker.
