摘要： A package for the storage of food or other suitable products includes a tray and, optionally, a lidding film. The tray is thermoformed, molded, or otherwise shaped to provide a recessed portion and flange, the recessed portion defining a product-receiving cavity. The flange includes a frame portion surrounding the cavity and a margin portion disposed alongside the frame portion and, in some embodiments, extending substantially a full width of the tray. The optional lidding film attaches to both the frame and margin portions and typically seals the cavity. The margin portion and a side wall of the recessed portion may include locking features to allow the margin portion to snap close against the side wall. The package may then be made to stand on end with the margin portion acting as a base. The lidding film may include a peelable/sealable film to allow repeated access to the product while sealing the cavity between uses.
