Technical Metal Foils – Industry Applications & Custom Solutions
Tailor-Made Solutions with Ultra-Thin Metal Foils
Whether lead foil, tin foil or non-ferrous metal foils – EppsteinFOILS develops and manufactures ultra-thin metal and composite foils for demanding technical applications. From X-ray technology and medical devices to photovoltaics, sensors and materials testing – our foils are engineered to meet precise functional requirements across a wide range of industries.
With decades of experience, a strong network of partners, and state-of-the-art manufacturing technologies, we translate individual customer requirements into high-precision solutions – from plain metal foils to laminated, coated or functionally enhanced composites.
Our foils stand out through targeted functional properties, excellent processability, and outstanding quality – the foundation of our leading position in the market for ultra-thin technical metal foils.
Application-Oriented Material Diversity
Our metal foils are available as plain foils or as laminated multilayer composites, which can be combined with materials such as plastic, paper, cardboard, nonwovens, or fabric. Additional surface coatings – such as lacquers – can be applied to achieve specific properties like insulation, barrier performance or functional enhancement.
Depending on the application, material requirements, and downstream processing, we adapt every solution individually – custom-tailored for technical use in a wide range of industries.
Typical Areas of Application:
- X-ray Technology & Imaging Equipment
(e.g. lead foil in dental films and X-ray grids) - Photovoltaics
(e.g. tin foil for solar cells and solder connections) - Medical Technology
(e.g. defibrillator foils, body electrodes) - Materials Testing & Metrology
(e.g. X-ray intensifying foils, test foils) - Electronics & PCB Industry
(conductive and insulating metal foils) - Packaging Technology
(e.g. food-grade tin foils with barrier coatings)
Material properties
Oxygen and Gas Barrier
The metallic density of our foils provides reliable protection against oxygen transmission – ideal for sensitive media and technical sealing applications.
Electrical Conductivity & Insulation
Our conductive metal foils (e.g. tin or non-ferrous foils) enable precise electrical control. When combined with non-conductive layers, they form functional insulation systems for complex electronic applications.
Corrosion resistance
Our corrosion-resistant foil solutions ensure longer service life in humid, aggressive, or electrically active environments.
Radiation Shielding
Lead foil and special composite foils offer high shielding performance against X-rays, gamma rays, and high-frequency radiation – for example, in medical diagnostics and non-destructive materials testing.
Food Contact Compliance
Our foils can act as barriers against migration and comply with the requirements of the German LFGB, EU Regulation (EC) No. 1935/2004, and PIM guidelines – making them suitable for food packaging and sensitive barrier applications.
Formability & Ductility
With excellent flexibility and mechanical adaptability, our foils are well-suited for technical seals or formable components in precision assemblies.
Low Melting Range
Ideal for soft soldering – including lead-free tin solder alternatives. This is especially relevant in photovoltaics, sensors, and microelectronics.
