What Is a Film Base?
A film base is a thin layer of material, typically made from plastics or metals, designed for various applications.
With thicknesses ranging from a few micrometers to several hundred micrometers, film bases are available in both roll and sheet forms. They consist of a primary substrate material—such as plastics or metals like aluminum and copper—and are often fortified with additives including antioxidants and stabilizers to boost performance. These materials are combined and processed to create the film base.
The versatility of film bases allows for their use in numerous industries, from printing and electronics to packaging, construction, and medical devices. In electronics, they serve as components in displays and touch panels; in construction, they are utilized for insulation and waterproofing; and in the medical field, they’re used in manufacturing artificial joints and medical imaging films.
