The invention relates to a method for preserving the stability of a hemoglobin blood substitute comprising maintaining the hemoglobin blood substitute in an atmosphere substantially free of oxygen. The method for preserving a deoxygenated hemoglobin blood substitute comprises maintaining the deoxygenated hemoglobin blood substitute in an oxygen barrier film overwrap package. In one embodiment, the package comprises a transparent laminate material comprising an oxygen barrier layer and a polyolefin layer, wherein the laminant has a thickness of between about 0.001 and about 0.01 inches (or about 0.0254 to about 0.254 millimeters) and an oxygen permeability of less than about 0.01 cubic centimeters per 100 square inches (or about 0.01 cc per 645 square centimeters) over 24 hours at 1 atmosphere and at about 23° C. The oxygen barrier layer comprises ethylene vinyl alcohol. Aso provided herein is a preserved deoxygenated hemoglobin blood substitute comprises a deoxygenated hemoglobin blood substitute and an oxygen barrier film overwrap package. The package comprises a transparent laminant material comprising an oxygen barrier layer and a polyolefin layer. Said oxygen barrier layer has an oxygen permeability of less than about 0.01 cubic centimeters per 100 square inches (or about 0.01 cc per 645 square centimeters) over 24 hours at 1 atmosphere and at about 27° C. room temperature, wherein the deoxygenated hemoglobin blood substitute is sealed within the overwrap package. In one embodiment, the oxygen barrier layer comprises ethylene vinyl alcohol.

The invention relates to a method for preserving the stability of a hemoglobin blood substitute comprising maintaining the hemoglobin blood substitute in an atmosphere substantially free of oxygen. The method for preserving the deoxygenated hemoglobin blood substitute comprises maintaining the deoxygenated blood substitute in an oxygen barrier film overwrap package, wherein at least one face of the overwrap package comprises a transparent laminate material and wherein at least one other face of the overwrap package comprises a foil laminate material. The preserved deoxygenated hemoglobin blood substitute comprises a deoxygenated hemoglobin blood substitute and an oxygen barrier film overwrap package wherein at least one face of the overwrap package comprises a transparent laminate material and wherein at least one other face of the overwrap package comprises a foil laminate material.

A method for manufacturing a transparent conductive film, said method comprising: forming a compound layer containing a silazane compound on a substrate; supplying energy to the compound layer and thus converting at least a part of the silazane compound into a compound having a siloxane bond to thereby modify the compound layer; and then forming a metal layer, that is configured from silver or an alloy comprising silver as the main component, on the unmodified compound layer or the modified compound layer.

A composite packaging material includes a top film and a bottom film as the forming film. The up film is BOPP / PE-TIE-PVDC-TIE-PP-PE structure, which is co-extruded by multi-layer flow or inflation film and formed by a solventless dry way; the bottom films has a PP-TIE-PVDC-TIE-PE structure which is co-extruded by multi-layer flow or inflation film. PVDC is homopolymerization of the polyvinylidene chloride or the copolymer of the methyl acrylate or the vinyl chloride, PE is polyethylene or modified polyethylene, and PP is polypropylene or modified polypropylene. The composite packaging material can solve the problem of effective composite of the PVDC-polyolefin material in the condition of the co-extruding, has high oxygen and water resistance, and can be used for various packages of gasing, vacuumizing and thermal forming.

Disclosed is a gas barrier resin composition which contains a polymer (A) having a repeating constitutional unit including an active hydrogen-containing functional group and / or a heteroatom-containing polar functional group, and an organic compound (B) containing an active hydrogen-containing functional group and / or a heteroatom-containing polar functional group in a molecule. Also disclosed is a gas barrier film containing such a gas barrier resin composition. The gas barrier resin composition and the gas barrier film have excellent gas barrier properties without containing a halogen.
