The presently disclosed subject matter is directed to a polymeric films suitable for use in a wide variety of applications, including (but not limited to) the formation of bioprocessing containers. Particularly, the disclosed films comprise a first barrier layer comprising polyglycolic acid, polyamide, EVOH, and/or an EVOH blend and a second barrier layer comprising EVOH. The dual barrier layers of the film maintain a high gas barrier under a variety of relative humidity conditions. In addition, the disclosed film is biologically inert and free from film surface-modifying additives such that the film does not inhibit the growth of biological cell cultures.
