    Abstract: This multilayer component (11) for encapsulating an element (12) which is sensitive to air and/or moisture comprises an organic polymer layer (1) and at least one barrier stack (2). The barrier stack (2) comprises at least one sequence of layers consisting of a retention layer (22) sandwiched between two high-activation-energy layers (21, 23), in which: - for each of the two high-activation-energy layers (21, 23), the difference in activation energy for water vapor permeation between, on the one hand, a reference substrate coated with the high-activation-energy layer and, on the other hand, this same reference substrate when bare is greater than or equal to 20 kJ/mol; and - the ratio of the effective water vapor diffusivity in the retention layer (22) on a reference substrate to the water vapor diffusivity in this same reference substrate when bare is strictly less than 0.1.

    Abstract translation: 用于封装对空气和/或水分敏感的元件（12）的该多层组件（11）包括有机聚合物层（1）和至少一个阻挡叠层（2）。 阻挡层叠（2）包括由夹在两个高活化能层（21,23）之间的保留层（22）组成的至少一个层序列，其中：对于两个高活化能中的每一个 一方面，涂覆有高活化能层的参考基底和另一方面，当裸露度更大时，相同的参考基底的水蒸气渗透的活化能的差异（21,23） 大于或等于20kJ / mol; 以及 - 当裸露严格小于0.1时，保留层（22）中参考基板上的有效水蒸气扩散率与该相同参考基板中的水蒸气扩散率的比率。
