Freshure® Coatings: Environmentally Friendly Barrier Coatings

Presented by Shahab Jahromi, Knowfort Technologies BV

Roll-to-roll vacuum deposition of hard materials (inorganic and metallic) has been the method of choice to producing functional coatings in various industries such as semiconductor and flexible packaging. Vacuum deposition of soft organic materials on the other hand is still in its infancy but recently gaining more interest from various industries such as consumer electronics specifically for the production of devices based on Organic Light Emitting Diodes (OLEDs).

Here we present production of functional coatings based on vapor deposition of a class of compounds named triazine. First we will shortly highlight various aspects of the technology including base material and process parameters. Then we will discuss major features of two applications of triazine based coatings, i.e. as a barrier layer in flexible food packaging and as organic layer in multi-stack thin films for encapsulation of OLEDs.
