Abstract: A packaging system having an outer container and a segment panel defining a plurality of phase change material (PCM) segments, with said segments being aligned with sides of the outer container interior upon wrapping around a payload and insertion into the outer container. The segmented panels may include edge tapers which facilitate the wrapping process with adjacent edge tapers being brought together during the wrapping process. A method of packaging using PCM-containing segments which are wrapped around a portion of a payload is also disclosed.

Abstract: A package and method of use for packaging temperature sensitive payloads during transport through environments having extreme temperatures. The package includes a segmented, flexible panel containing a plurality of phase change material segments. A pair of such panels may be used, with each panel being separately thermally preconditioned as a function of anticipated ambient temperature during transport. The panels may be formed by retaining phase change material segments between a pair of flexible sheets.
