Thermal Metalized Film is a functional material produced through processes such as vacuum evaporation or sputtering, which deposits an extremely thin metal layer (e.g., aluminum, copper, nickel, etc.) onto the surface of plastic films (such as polyester PET, polypropylene PP, etc.). Its core characteristics combine the high thermal conductivity, electrical conductivity, and reflective properties of metals with the flexibility and processing convenience of plastic films, making it widely used in electronics, new energy, packaging, thermal management, and other fields.
