Abstract: 1. A method of protecting at least one article from corrosion comprising placing at least one article to be protected in a gas impermeable enclosure and at least one corrosion preventing device is selected from a desiccant, a corrosion inhibitor, an inert gas, or a combination thereof, and sealing the gas impermeable enclosure, wherein the gas impermeable enclosure comprises at least two gas impermeable shells the pressure inside the enclosure and between the shells is greater than the external pressure and the inside the enclosure is less than the pressure inside the space between the shells. 2. A method of protecting at least one article from corrosion comprising placing at least one article to be protected in a gas impermeable enclosure and at least one corrosion preventing device is selected from a desiccant, a corrosion inhibitor, an inert gas, or a combination thereof, and sealing the gas impermeable enclosure, wherein the gas impermeable enclosure comprises at least two gas impermeable shells the pressure inside the enclosure and between the shells is greater than the external pressure and the inside the enclosure is greater than the pressure inside the space between the shells. 3. The method of claim 1 or 2, wherein the at least two shells are formed from a gas impermeable structure which contains at least one layer which is selected from a gas impermeable polymer layer, a metal layer, or fabric layer. 4. The method of claim 3, wherein the at least one polymer layer is formed from at least one polyolefin polymer. 5. The method of claim 3, wherein at least one desiccant and/or corrosion inhibitor is contained within the gas impermeable polymer layer and/or fabric layer. 6. The method of claim 4, wherein the polyolefin polymer is selected from polyethylene, polypropylene and ethylene/vinyl acetate copolymers. 7. The method of claim 1 or 2, wherein the gas impermeable enclosure further comprises a delivery system for delivering periodic doses of a desiccant, corrosion inhibitor and/or inert gas. 8. The method of claim 7, wherein the gas impermeable enclosure further comprises a monitoring system for monitoring at least one internal pressure inside the gas impermeable enclosure. 9. The method of claim 8, wherein the gas impermeable enclosure further comprises an alarm system for signaling a drop in the at least one internal pressure. 10. The method of claim 1 or 2, wherein at least one desiccant, corrosion inhibitor and/or inert gas is contained in the space between the inner and outer shells. 11. The method of claim 1 or 2, wherein at least one desiccant, corrosion inhibitor and/or inert gas is contained in the space between the inner and outer shells, and at least one desiccant, corrosion inhibitor and/or inert gas is contained inside the inner shell. 12. The method of claim 1 or 2, wherein at least one desiccant, corrosion inhibitor and/or inert gas is contained inside the inner shell. 13. The method of claim 1 or 2, wherein the enclosure is accomplished using a heat sealing, an adhesive seal, or a mechanical sealing means. 14. A corrosion protection system comprising a gas impermeable enclosure for holding at least one article to be protected and at least one corrosion preventing device placed inside the gas impermeable enclosure and selected from a desiccant, a corrosion inhibitor, an inert gas, or a combination thereof, wherein the gas impermeable enclosure comprises at least two gas impermeable shells the pressure inside the enclosure and between the shells is greater than the external pressure and the inside the enclosure is less than the pressure inside the space between the shells. 15. A corrosion protection system comprising a gas impermeable enclosure for holding at least one article to be protected and at least one corrosion preventing device placed inside the gas impermeable enclosure and selected from a desiccant, a corrosion inhibitor, an inert gas, or a combination thereof, wherein the gas impermeable enclosure comprises at least two gas impermeable shells the pressure inside the enclosure and between the shells is greater than the external pressure and the inside the enclosure is greater than the pressure inside the space between the shells. 16. The system of claim 14 or 15, wherein the at least two shells are formed from a gas impermeable structure which contains at least one layer which is selected from a gas impermeable polymer layer, a metal layer, or fabric layer. 17. The system of claim 16, wherein the at least one polymer layer is formed from at least one polyolefin polymer. 18. The system of claim 16, wherein at least one desiccant and/or corrosion inhibitor is contained within the gas impermeable polymer layer and/or fabric layer. 19. The system of claim 17, wherein the polyolefin polymer is selected from polyethylene, polypropylene and ethylene/vinyl acetate copolymers. 20. The system of claim 14 or 15, wherein the gas impermeable enclosure further comprises a delivery system for delivering periodic doses of a desiccant, corrosion inhibitor and/or inert gas. 21. The system of claim 20, wherein the gas impermeable enclosure further comprises a monitoring system for monitoring at least one internal pressure inside the gas impermeable enclosure. 22. The system of claim 21, wherein the gas impermeable enclosure further comprises an alarm system for signaling a drop in the at least one internal pressure. 23. The system of claim 14 or 15, wherein at least one desiccant, corrosion inhibitor and/or inert gas is contained in the space between the inner and outer shells. 24. The system of claim 14 or 15, wherein at least one desiccant, corrosion inhibitor and/or inert gas is contained in the space between the inner and outer shells, and at least one desiccant, corrosion inhibitor and/or inert gas is contained inside the inner shell. 25. The system of claim 14 or 15, wherein at least one desiccant, corrosion inhibitor and/or inert gas is contained inside the inner shell.
