Nanoparticles of amorphous aluminum oxynitride or silicon oxynitride having a very high aspect ratio are used to fill polymeric materials to provide products that have an extremely low WVTR/OTR. Such products are particularly effective for incorporation into organic light-emitting devices or the like which are susceptible to degradation from moisture and/or oxygen. Pressure sensitive and/or thermosetting adhesives filled with such particles create excellent sealants. Polymeric sheets or films made from resin in which these nanoparticles are dispersed, or intimately associated with, before extrusion exhibit very low WVTR/OTR.
