Business
Sungmoon Electronics Co., Ltd. manufactures metallized films for film capacitors, serving as core components in the electrical and electronics industry. The company produces ZN-deposited films, Al-deposited films, metallized polyester films, metallized polypropylene films, heavy edge films, wave cut films, Al-Zn metallized films, double heavy edge type films, and series type films; it also develops advanced products including AR barrier films, DECO films, and retroreflection films for future growth. Sungmoon Electronics operates production facilities in South Korea and China, with global marketing targeting markets in Asia, the Americas, and Europe. Founded in 1980 and headquartered in Pyeongtaek, South Korea, the company listed on the Korea Exchange in 1990 following collaborations with the Korea Advanced Institute of Science and Technology (KAIST) to localize metal deposition film technology. In August 2025, Sungmoon Electronics participated as a new investor in a CNY 37.5 million funding round for Jiangsu Qicheng New Materials Co., Ltd., issuing common shares to support strategic expansion in the materials sector. The company continues to invest in proprietary roll-to-roll (RTR) thin film deposition equipment to advance energy applications and maintains a focus on research and development for high-performance capacitor films.
