ABSTRACT:
The presently disclosed subject matter is directed to a barrier film that maintains an oxygen barrier after being subjected to autoclaving conditions. The film comprises one EVOH layer positioned as a core layer, and one EVOH layer positioned directly adjacent to an outer layer comprising highly permeable material having a moisture vapor permeability greater than about 40 g-mil/100 in2-day-atm. During autoclaving, the barrier properties of the EVOH layer positioned adjacent to the outer layer allows improved recovery of oxygen barrier properties. In addition, during rewetting applications, the internal EVOH layer maintains the oxygen barrier. Also disclosed are methods of making and using the disclosed barrier film.
