A cover sheet of paper or the like is laminated with a liner blanket of plastic material embodying closely spaced and hermetically sealed air cells. The composite sheet or mat is doubled upon either its longitudinal or its transverse center line to form a folder-shaped body with the cellular blanket inside. Two of the three open borders are heat sealed, hinged over upon and secured to the adjacent exterior surfaces of the body, thus completing a pressure cushioning and heat insulating container. The open border of the container is preferably crushed or compressed, to thin its walls for convenience in filling and subsequent closure.
