![]() Commonly used metallized plastics have sufficiently low permeation rates for most applications, but lose their utility when product visibility is desired, as in food packaging, or even a requirement, in the case of FOLEDs. Similar layers with very low permeation rates to atmospheric gases are also key components for a variety of packaging applications, including food and pharmaceuticals. atm) to achieve sufficient performance requirements (i.e., tens of thousands of hours of operation) in ambient environments.These devices require an oxygen transmission rate (OTR) below 10 −5 cc/(m 2 BACKGROUND OF THE INVENTIONĬurrent flexible display architectures, such as those used for flexible organic light emitting diodes (FOLEDs), require a transparent barrier layer that prevents oxygen gas ingress into the device's active components. The multilayer film is an effective barrier for humidity and oxygen. The present invention is directed to a multilayer barrier film prepared by a layer by layer process.
