The package includes a multilayered polymeric tray (10, 20) having a basin (30) and a brim (34) and optionally a spout (32) extending from the basin and in such cases the basin and the spout terminate in the brim. The tray (10, 20) is comprised of a plastic structural layer and a bonding layer. A multilayered polymeric cover (40) has a cross-oriented, tear-resistant layer, a bonding layer, and a moisture-barrier layer between the tear-resistant layer and the bonding layer of the cover. The bonding layer of the cover is sealed to the bonding layer of the brim of the tray to form a closed cavity between the tray and the cover.
