SANGBOCo

SANGBOCo makes coated films, thin plastic sheets applied to car and building windows to block heat, infrared and ultraviolet light, and to hold glass together if it shatters.

It also supplies paint-protection film (PPF), a clear layer applied to vehicle surfaces to guard against scratches and contamination. Listed on KOSDAQ, Korea's tech and small-cap board, the company draws the majority of its revenue from these window and protection films, split between domestic and export markets. It is also developing barrier films used in quantum-dot displays and electronic shelf-label technology as a newer business line.
