Zusammenfassung:	A multilayer film is provided having barrier protection for high acid foods. The film generally comprises an inorganic core layer comprising a substrate layer upon which an inorganic barrier layer is disposed and at least one outer barrier layer. The outer barrier layer has a core layer that may consist of a barrier layer surrounded by two outer sealant layers. The composite maintains excellent barrier properties at higher temperatures and humidities in order to maintain shelf stable package after it is aseptically or hot filled. The barrier properties of the composite is not significantly affected upon flexing of the film.
