ABSTRACT:
The object of the present invention is to provide a gas barrier film suitable for medical uses, which is excellent in gas and vapor properties and can prevent ingredients of an adhesive and the like from eluting even after heating and sterilizing treatment, and a medical bag using the gas barrier film. A medical gas barrier film of the present invention comprises a multilayer gas barrier film10including a deposition oriented polyester layer11having a deposited layer13of an inorganic oxide on one surface, an oriented polyamide layer15adhered to the surface of the deposited layer13and a polyethylene layer17adhered to the surface on the opposite side to an adhered surface15aof the oriented polyamide layer15, and a multilayer substrate film22including a cyclic olefin polymer layer25, an elastomer layers24, 26and a heat sealing layer23, and the multilayer substrate film22is adhered to an other surface11bon the opposite side of the deposited layer of the deposition oriented polyester layer11.
