A packaging device includes upper and lower container portions that support respective frames that, in turn, support respective support films. The frames and the container portions are configured such that the act of installing the frames in the container portions automatically increases tension in the films. This can be accomplished by rotating opposed portions of the frames in opposite directions, by displacing the film out of the plane in which it is originally supported by the frame, or by displacing opposed portions of the frame away from one another. The film of the lower container portion is recessed with respect to a peripheral lip of the lower container portion, while the film of the upper container portion protrudes beyond the peripheral lip of the upper container portion. In this way objects are prevented from rolling out of the lower container portion, yet the films are brought into face-to-face contact when the packaging device is closed.
