ABSTRACT:
A thermal insulating material is packed in a sealing bag composed of an obverse face material and a reverse face material, wherein each of the obverse face material and reverse face material is preferably made of a metal foil having a thickness in the range of 3 to 50 micrometers and which is sandwiched by a sealant layer of plastic film adhesively affixed to one side thereof and by a surface layer of plastic film adhesively affixed to the other side thereof (hereinafter termed a metal foil composite plastic film), and then a similarly constructed metal foil composite plastic film, or preferably one having a number of holes therein, is stuck on the outer surface or inner surface of the obverse face material, to thus obtain a vacuum thermal insulating panel. The vacuum thermal insulating panel thus obtained can prevent permeation of gas from the outside, reflect heat, and prevent heat conduction along the outer surface.
