PURPOSE: An aluminum film for a thermal reflection insulating material is provided to prevent contamination and corrosion and improve the insulation performance of a thermal reflection insulating material. CONSTITUTION: An aluminum film for a thermal reflection insulating material comprises a polyethylene terephthalate film for improvement of tensile and adhesion strength, a pure aluminum layer which is formed on one or both sides of the polyethylene terephthalate film, and an oxidation prevention layer which is formed on the outer side of the aluminum layer, where the polyethylene terephthalate film is not formed, by coating oil-printing solvent to the thickness less than 6μm over the entire surface in order to prevent contamination and oxidation and maintain reflectivity of 95% or greater and emissivity of 0.05 or less. The aluminum film layer and the oxidation prevention layer are hardened through thermal rollers of 150°C-200°C.
