The manufacturing plant located in Pocheon, Gyeonggi Province, is equipped with various facilities for production, so all processes are carried out at once. In 2017, it developed a copper antibacterial film that maintains an antibacterial function even if the surface is peeled off for the first time in Korea and abroad and completed patent registration. We received 99.9% antibacterial power and 1st grade anti-fungi for E. coli, Staphylococcus aureus and pneumococcus from SGS, the world's leading testing agency. Starting with this, it is recognized as a domestic interior finish manufacturer by applying antibacterial technology to each product and introducing differentiated products such as PVC interior film, decoration sheet, PVC flooring, and premium interior board.
