Seoil's advanced Al metallization technology begins with the rigorous management of core properties such as Optical Density (OD), Visible Light Transmission (VLT), surface resistance, barrier characteristics, and gloss.
By introducing the Manufacturing Execution System (MES) to the Almetalized film production line, Seoil successfully optimized the entire process, enabling real-time quality control and the efficient distribution of technical data sheets. We provide the best-quality products and services to our customers.
We also provide customized products which are designed and manufactured according to the customer requirements. A wide range of flexible packages or functional films can be produced as needed by tailoring the coating and slitting processes.
