Title: Insulating vacuum panel, method for manufacturing the insulated vacuum panel and insulated containers employing such panel

Abstract: An insulating vacuum panel comprising a microporous, open cell silica foam or a precipitated silica insulating support member enclosed within a sealed, flexible polymeric envelope, the envelope comprising a heat-sealable barrier film comprising a multiple layer laminate containing at least one polyethylene terephthalate layer and at least two barrier layers selected from the group consisting of polyvinylidene chloride, polyvinyl alcohol, polyamide, polyolefin and aluminum foil, or a biaxially oriented liquid crystal barrier film which minimizes permeation of gas and liquid through the barrier film, the panel having an R value per inch of at least about 20 wherein the enclosed insulated vacuum panel is useful as insulation to maintain an essentially constant temperature in a closed structure, a system for storing and transporting temperature-sensitive materials wherein the insulated vacuum panels are employed to provide and maintain a constant temperature in the system, a method for manufacturing the insulating vacuum panel, and a system for storing and transporting temperature-sensitive materials are described.
