Hot stamping foil, also known as hot stamping paper, is commonly known as anodized aluminum in northern my country. It is composed of polyester film (PET) and a multi-layer chemical coating coated on its surface.

　　Its structure is: a base layer, a peeling layer, a color layer, an electroplating layer, and a glue layer. Some of these coatings are used to create a decorative effect, while others are used to control the properties of the foil, and different coatings are suitable for different substrates. The function of the aluminum layer is to produce a reflective effect, which is formed by the aluminum wire being melted and sublimated at high temperature and condensed on the bronzing paper under ultra-low vacuum conditions.

　　Hot stamping process is also called hot stamping or hot anodized aluminum foil. Anodized aluminum is composed of five layers of different materials, the first layer of base film layer, the second layer of peeling layer, the third layer of coloring layer, the fourth layer of aluminized layer, the fifth layer layer of hot melt film. The hot stamping principle is that when the anodized aluminum is heated, the second layer is melted, and then the fifth layer is also melted. During stamping, the hot-melt film layer adheres to the substrate, the third layer is separated from the first layer, and the aluminized layer and the coloring layer are separated. remain on the substrate. Therefore, the perfect hot stamping effect mainly depends on the temperature, pressure and hot stamping time.

　　The primary task of the hot stamping process is to select the hot stamping foil. The nature of the hot stamping foil adhesive layer determines its adaptability to the product material. If the bronzing paper is not selected properly, any adjustment of the bronzing process will be futile. Hot stamping foil must pass the test before it can be officially produced.
