The second sheet extends over at least three of the walls. The opposing container walls each have a sealed portion and one or more tucks, the tucks comprising a portion of the first sheet tucked toward the interior volume. A portion of the second sheet defines a recloseable feature located over an opening for reclosing the container. The second sheet includes a line of reduced strength at or adjacent at least a boundary adjacent the tucks and disposed between the opposing container walls each having the sealed portion and an adjacent container wall. The second sheet can include a hinge about which the recloseable feature pivots from closed position to open position.
