Method and system for storing and/or transporting temperature-sensitive materials

Abstract

Method and system for maintaining temperature-sensitive materials within a desired temperature range for an extended time. In one embodiment, the system includes an outer box having a rectangular cavity. An insulation unit is snugly but removably positioned in the rectangular cavity. The insulation unit includes a support and a thermal insulation member. The support may be a generally rectangular sleeve with four sides, an open bottom and an open top. The thermal insulation may be a bilayer material wrapped around the four sides of the support to form a spiral structure. The bilayer material may include a first sheet of an expanded slit-sheet packaging material and a second sheet of tissue paper. The system may additionally include a bottom insulation member at the bottom of the support, a top insulation member at the top of the support, and a payload and temperature-control members between the top and bottom insulation member.
