A method of packaging thermally labile goods. The method includes the steps of (a) obtaining a legend correlating thermally labile goods with a PCM panel color, (b) locating the thermally labile goods to be packaged on the legend and identifying the correlated PCM panel color, (c) obtaining thermally conditioned panels of the correlated PCM panel color from amongst a plurality of differently colored thermally conditioned panels color coded in relation to the phase change temperature of the phase change material contained within the panels, (d) lining the retention chamber of a thermally insulated container with the obtained thermally conditioned PCM panels, (e) placing the thermally labile goods to be packaged into the lined retention chamber, and (f) closing the container.
