ABSTRACT:
The present invention is directed to a transport package which efficiently maintains payload temperature within a predetermined temperature range during delivery through regions having ambient temperatures outside the desired range. The transport package is used for transporting temperature sensitive materials and thermally protecting the materials from cold and hot ambient temperatures in a manner that does not require a power source or other mechanical devices. Aspects of the invention relate to a temperature maintaining packaging system having an outer container, thermal insulation materials and two or more different phase change materials.
