The bronzing process utilizes the principle of heat transfer to transfer the aluminum layer in the galvanized aluminum to the surface of the substrate to form a special metal effect. Since the main material used for the bronzing is the galvanized aluminum foil, the bronzing is also called galvanized aluminum hot stamping. Electrochemical aluminum foil is usually composed of multiple layers of material, often the substrate is P E, followed by the separation coating, color coating, metal coating (aluminum plating) and glue coating.
In the printing industry, electronic foils are commonly used for hot stamping on paper, which is called bronzing. Hot stamping is a collective term for a process. Stamping does not mean that gold is hot. There are many kinds of gold foil paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.
