A packaging assembly for holding contents is provided. The packaging assembly includes a self-supporting liner having a wall that encloses sides and bottom of an interior of the liner and defines an open top end of the liner, and a rim that projects outwardly from the wall proximal to the open top end. The packaging assembly also includes a lidding assembly including a cover region and a destructible seal region that seals the cover region to the liner extending over and closing the liner open top. The destructible cover region is weaker than the liner and the cover region so that detachment of the cover region from the liner causes the destructible seal region to fail. The lidding assembly includes a first lidding material having a center portion and an outer portion that surrounds the center portion.
