Methods disclosed herein include methods of manufacturing integrally thermally-sealed storage containers. Methods include creating at least one indentation in at least one layer of first thermal barrier sheet, wherein the at least one layer of first thermal barrier sheet includes at least one first ultra efficient insulation material and wherein the at least one indentation is in a size and shape substantially conforming with material to be stored; placing material to be stored within one or more of the at least one indentation; placing at least one layer of second thermal barrier sheet adjacent to the material to be stored, wherein the at least one layer of second thermal barrier sheet includes at least one second ultra efficient insulation material; and creating a thermal seal between at least two layers of thermal barrier sheet, substantially thermally sealing the material to be stored.
