GL FILM is a transparent vapor deposition film market and is sold worldwide, mainly for packaging material applications. Transparent vapor deposition films are functional films coated with inorganic film on the surface through vapor deposition processing. There have an inorganic vapor deposition barrier layer (alumina, silicon oxide, etc.) and coating barrier layer on the substrate film (PET, nylon, etc.). The multiple layer structure exhibits superb functionality combining Toppan's original coating layer and high-quality vapor deposition layer. This structure enables stable barrier performance and facilitates backend processes including printing and lamination. Transparent vapor deposition films feature both high barrier performance and transparency.
