Abstract
A packaging container is integrally formed from plastic foam material, such as extruded polystyrene foam. The packaging container has a base, four sidewalls extending from the base, and four corners, each extending between a pair of adjacent sidewalls. The sidewalls have substantially rectangular protrusions extending from the base to a top edge to strengthen the sidewalls against lateral forces. The sidewalls may also have rounded ribs which protrude into the interior of the packaging container for further reinforcement.
