How does it work? 
Under vacuum conditions and above its sublimation temperature of 200°C, triazine can cover large surface areas in a fraction of a second, creating a nano-layer of transparent crystalline coating with very high gas barrier properties.  This can be achieved via a roll-to-roll coating process at speeds higher than 10m/s, on films substrates such as BOPP, PET, OPA, CPP and PLA.
