Abstract
A barrier stack for encapsulating a moisture and/or oxygen sensitive electronic device is provided. The barrier stack comprises a multilayer film having at least one barrier layer having low moisture and/or oxygen permeability, and at least one sealing layer arranged to be in contact with a surface of the barrier layer, wherein the sealing material comprises reactive nanoparticles capable of interacting with moisture and/or oxygen, thereby retarding the permeation of moisture and/or oxygen through defects present in the barrier layer.
