Beschreibung
Zusammenfassung:	The invention relates to a composition comprising a film having at least two polymeric moisture barrier layers and at least one extruded oxygen barrier layer positioned between the polymeric moisture barrier layers. The extruded oxygen barrier layer includes a blend of (i) a polyethylene oxide component and (ii) an alkoxy silane component, which helps the film in retaining oxygen barrier properties even under high humidity. The film further exhibits reduced tendency for delamination and retains excellent flexibility. The invention further describes methods of preparing such a composition using a combination of an extrusion process and a lamination process.
