Zusammenfassung:A package is provided for controlling the atmospheric condition of a packaged product and includes first and second package walls sealed at their peripheries to define a product cavity therebetween. One package wall is formed from a gas impermeable material and the second package wall includes a composite of an inner gas permeable layer and an outer gas impermeable layer. The outer layer is adapted for removal from the inner layer without destroying the seal between the first and second package walls so as to allow gases to flow through the inner layer and to thereby change the atmospheric condition of the packaged product.
