A method of improving the storage life of goods by storing the goods in an environment comprising heptafluoropropane at pressures of between about 0.1 atmospheres and about 2.0 atmospheres. Foods, pharmaceuticals, and other goods adversely affected by oxygen and/or moisture are effectively stored by the claimed method. The method is particularly effective for goods stored in plastic containers, and for goods stored in containers stoppered by rubber stoppers.
