FLEXIBLE BARRIER FILMS CONTAINING CYCLIC OLEFINS

A multilayer barrier film is described which defines a central plane, the barrier film comprising a plurality of layers each including at least one cyclic olefin copolymer (COC) containing norbornene, the concentration of norbornene in each layer of the plurality of layers decreasing with increased...

Beschreibung
Zusammenfassung:	A multilayer barrier film is described which defines a central plane, the barrier film comprising a plurality of layers each including at least one cyclic olefin copolymer (COC) containing norbornene, the concentration of norbornene in each layer of the plurality of layers decreasing with increased distance from the central plane. Further, an article comprising the multilayer barrier film is provided.
