The invention relates to a foamed thermoplastic packaging structure designed to package eggs and the like. The package includes a body section and the body has a plurality of downwardly directed deep egg receiving pockets. All adjacent pockets are separated by at least one flexible thin-walled separator which prevents substantial contact and which provides resilience and flexibility between the eggs positioned in the pocket. The separator is formed by upwardly directed extension walls formed continuously with and extending upwardly from the pocket walls of the adjacent pockets. Each of the extension walls terminates in individual upper end walls, and the walls of the pockets have individual relatively thick cross-sections of from 30 to 120 mils to provide structural strength in the structure. The walls of the separator have individual relatively thin cross-sections of at least 5 mils to prevent substantial contact and to provide resilience and flexibility between the eggs in the pockets. In accordance with the invention, the ratio of cross-sectional width of the thick walls to the crosssectional width of the thin walls is from 1.2 to 24.
