Beschreibung
Zusammenfassung:	Provided is a barrier film capable of having both barrier properties after a Gelbo flex test and barrier properties after a retort treatment. This barrier film comprises a resin base, an aluminum oxide vapor deposition film, and an optional covering layer, which are layered in the stated order. The peak top ratio P, as defined in the following, of the aluminum oxide vapor deposition film is not less than 0.70 but less than 1.05 as measured by X-ray absorption microstructural analysis conducted from the aluminum oxide vapor deposition film side of the barrier film. P = (intensity peak top at or near 1572 eV)/(intensity peak top at or near 1566 eV).
