NOVELTY - The invention claims a high-stability double-face copper box Mylar structure, comprising a first copper foil layer, nano-silver flexible conductive film, mylar; a graphene film and a second copper foil layer; one side surface of the mylar piece is adhered and fixed with nano-silver flexible conductive film; the surface nano-silver the flexible conductive film is adhered and fixed with a first copper foil layer; the outer surface of the first copper foil layer is coated with a radiating silicone grease layer; the outer surface of the radiating silicone grease layer is adhered with a first release paper. The invention has reasonable structure, convenient use, two sides of the invention is provided with an easy tearing gap; it is more convenient to tear; at the same time, the tearing resistance is smaller, the use is more convenient; the application passes through the outer surface of the radiating silicone grease layer, so that the contact piece between the heat conducting effect is better; so that the radiating performance is improved, so that the long time use is more stable.
