Abstract
Provided is a barrier film provided with a deposition film formed on an OPP film base material and, if necessary, a covering layer, which enables both deterioration of barrier properties after the heat sterilization treatment, and the Gelbo Flex resistance. The present invention provides a barrier film comprising a polypropylene base material, a base layer, and an aluminum oxide deposition film, laminated in this order, wherein the aluminum oxide deposition film has an intensity ratio P1 of 0.090 or more and 0.170 or less defined by the following equation when X-ray absorption fine structure analysis is performed from a surface opposite to the polypropylene base material side of the barrier film, P1 = (average intensity from 1561.0 eV to 1563.6 eV)/(average intensity from 1566.5 eV to 1571.6 eV). <img class="EMIRef" id="282f9bc6-8951-475c-bf1c-305bbc9ce705-ia01" />
