ABSTRACT:
A thermal pack including an outer pouch having a pair of opposed faces arranged generally parallel to each other and defined by a single sheet of plastic film folded along a predetermined fold line. A second sheet of plastic film is disposed between the pair of opposed faces. A continuous weld line circumscribes the periphery of the faces, with the weld line bonding together the periphery of the faces and the periphery of the second sheet to define first and second volumes within the outer pouch. The second sheet provides a common wall between the first and second volumes. A heat transfer material is disposed in the first volume and an insulating layer is disposed in the second volume, substantially covering the second sheet.
