NOVELTY - In applications requiring barrier properties resistant to high humidity, vapor deposited melam on a substrate, is used.    USE - In applications requiring barrier properties resistant to high humidity, where the applications comprise as barrier layer in retortable laminate, as undercoat and/or topcoat in metal coated paper, as barrier layer in solar or display applications, and in laminates (claimed) useful in packaging for microwaveable food applications, and in electronic industries. Also useful for the encapsulation of flexible displays like liquid crystalline displays, organic light emitting diode displays, polymer light emitting displays, electrophoretic displays, electroluminescense displays, or phosphorescent displays.    ADVANTAGE - The vapor deposited melam coatings are able to withstand high humidity and high temperature. The laminates comprising melam barrier layer have good barrier properties and good lamination strength, which is microwaveable and retortable, i.e. preserve barrier properties after retort process and are suitable for hot filling and/or boiling, i.e. preserve barrier properties after such processes. The metal coated paper or carton based package comprising the melam coatings have good barrier properties with in-line coating layers. The melam coatings provide sufficient protection to rigid or flexible electronic devices such as displays and solar cells against external environment like moisture. Application of melam, directly on top of the organic light emitting diode (OLED) molecules as the top layer, significantly increases the life time of such displays without the need to apply various types of sealing systems. It is also possible to coat the melam layer with various types of vapor depositable compounds such as fluorine based compounds, to increase the moisture barrier. The crystalline melam layers are well suitable for use in an application as barrier coatings with desirable optical characteristics, i.e. this triazine compounds does not absorb in long wavelengths (greater than 500 nm). This is an advantage over inorganic transparent barrier materials and thus potential applications in electronic devices. The melam layer can be applied directly on a substrate, like a plastic film as a sole barrier layer, but can as well be used as layer on other barrier layers such as metal or metal oxide layers. Furthermore, when used on a metal layer, melam has good adhesion and insulating properties, allowing a further metal layer to be applied. The use of melam has the advantage, that the temperatures which are regularly applied (up to 400 degrees C) can be used as such. In contrast, it is necessary to lower the temperature of the lamination if melamine is used as triazine. A metal or metal oxide layer can be directly deposited on a melam layer and the combined structure has improved oxygen and water barrier properties. In case of melamine, it is not possible to deposit a pristine layer of metal or metal oxide on top of melamine, because, due to thermal heating of the metal or metal oxide layer, melamine tends to sublime upon deposition of metal or metal oxide layer. Melam, due to its lower vapor pressure and higher sublimation temperature, does not sublime upon vapor deposition of metal or metal oxide layer resulting in formation of a pristine layer on top of melam.
