1. A method of manufacturing a biodegradable insulative shipping container, comprising:
providing a substantially rectangular shaped outer tray comprising a pulp material, the outer tray having a bottom panel and side walls that extend substantially perpendicularly to each other and the bottom panel;
providing an inner tray comprising a pulp material, the inner tray having a top, a peripheral edge at the top, the peripheral edge substantially rectangular and including four flaps extending outwardly therefrom and bendable to extend downwardly therefrom, and an irregular concave valley including a continuous surface that extends downwardly from the peripheral edge to define an interior volume adapted to receive a good;
creating a void between the concave valley and the bottom panel of the outer tray by aligning the peripheral edge of the inner tray with the side walls of the outer tray;
prior to combining the outer and inner trays, filling the void with biodegradable insulative material by placing an insulation tray comprising an extruded starch material in the void between the inner tray and outer tray; and
sealing the insulative tray between the inner tray and the outer tray.
