Embodiments of the invention relate to a cover, a method of covering, and a cover system to be used with shipments of products transported by air with ULDs. The dimensions of the cover system can vary depending on the ULD they are designed to be used with. The cover system can also be adapted to any individual skid such as wooden or plastic pallets used for smaller loads used in air transport or any other mode of transportation. The cover system can include one or multiple parts that wrap the shipment. Each part of the cover system can be made of one or more layers. Each layer can be made of a single material or a combination of different materials, and different layers can incorporate different materials. The different parts of the cover can be made of different materials or different combination of materials. In specific embodiments, materials used for the cover system are Radio Frequency Identification (RFID) friendly. The cover system provides thermal protection to temperature-sensitive products in or on the ULD. The cover system maintains the proper relative humidity level and gas concentrations (oxygen, carbon dioxide and ethylene) for horticultural product loads. The cover system can also have antimicrobial properties. In addition, the cover system decreases the amount of water vapor released in the cargo holds which is known to affect the reliability of the aircraft smoke detection system and to cause false fire alarms.

1. A method for covering a load on a unit load device or on a skid, comprising: covering a load on a unit load device or on a skid transported by air,securing the cover in a covered position around the load on or in the unit load device or on the skid, wherein the cover provides thermal protection t
1. A method for covering a load on a unit load device or on a skid, comprising: covering a load on a unit load device or on a skid transported by air,securing the cover in a covered position around the load on or in the unit load device or on the skid, wherein the cover provides thermal protection to the load on or in the unit load device or on the skid from conductive and convective heat transfer,wherein the cover has a permeance for oxygen of at least 15.6×103 Lo2/(m2 atm d),wherein the cover has a permeance for carbon dioxide of at least 23.4×103 Lco2/(m2 atm d), andwherein the cover has a permeance for water vapor between 1×103 gwater(m2 atm d) and 50×103 gwater/(m2 atm d). 2. The method according to claim 1, wherein the cover is adapted for covering various size loads on the unit load device or on the skid. 3. The method according to claim 1, wherein the cover comprises an outside surface with physical properties affecting radiative heat transfer with the surrounding environment in such a way that the cover helps to maintain the temperature of the load. 4. The method according to claim 1, wherein the cover comprises a single layer. 5. The method according to claim 1, wherein the cover comprises multiple layers. 6. The method according to claim 1, wherein the cover comprises multiple parts. 7. The method according to claim 6, wherein a first of the multiple parts has a first permeance for oxygen and a first permeance for carbon dioxide, wherein a second of the multiple parts has a second permeance for oxygen and a second permeance for carbon dioxide, wherein the first permeance for oxygen is different than the second permeance for oxygen and the first permeance for carbon dioxide is different than the second permeance for carbon dioxide, wherein the permeance for oxygen is determined by the first permeance for oxygen, the second permeance for oxygen, and permeances for oxygen of any other of the multiple parts, wherein the permeance for carbon dioxide is determined by the first permeance for carbon dioxide, the second permeance for carbon dioxide, and permeances for carbon dioxide of any other of the multiple parts. 8. The method according to claim 1, wherein the cover allows the respiration of horticultural products by providing adequate gas exchange rates of oxygen and carbon dioxide between the load and the surrounding environment. 9. The method according to claim 1, wherein the cover allows water vapor exchange between the load and the surrounding environment. 10. The method according to claim 9, wherein the water vapor exchange between the load and the surrounding environment acts to maintain a level of relative humidity to avoid condensation on the load. 11. The method according to claim 1, wherein the cover allows the exchange of gases between the load and the surrounding environment. 12. The method according to claim 11, wherein when the load is horticultural products the exchange of gases between the load and the surrounding environment acts to allow the respiration of the horticultural products by providing adequate gas exchange rates of oxygen and carbon dioxide between the horticultural products and the surrounding environment. 13. The method according to claim 1, wherein for a covered load loaded in an aircraft cargo hold, the cover allows the exchange of water vapor between the load and the aircraft cargo hold environment so as to avoid a release of water vapor in the aircraft cargo hold sufficient to trigger an aircraft cargo hold compartment smoke detection system. 14. The method according to claim 1, wherein the cover comprises a material that absorbs or eliminates ethylene. 15. The method according to claim 14, wherein a concentration of ethylene around the load is <0.01 ppm. 16. The method according to claim 1, wherein the cover comprises a material imbedded or coated with antimicrobial agents that will decrease and/or stop the growth of microorganisms and/or kill microorganisms. 17. The method according to claim 1, wherein the cover protects the covered shipment from one or more of the following: precipitation, condensation, dust, wind, insects, and small animals. 18. The method according to claim 1, wherein the cover is made entirely or partially from a material or a combination of materials that is RFID friendly. 19. The method according to claim 1, wherein the cover allows the use on and/or under the cover system of RFID tags such as but not limited to passive, semi-passive, active, semi-active. 20. The method according to claim 1, wherein the cover is perforated. 21. The method according to claim 1, wherein the cover comprises flash spun polyolefin. 22. The method according to claim 1, wherein the cover has a homogeneous permeance for oxygen of at least 15.6×103 LO2/(m2 atm d) and a homogeneous permeance for carbon dioxide of at least 23.4×103 LCO2/(m2 atm d). 23. The method according to claim 1, wherein an oxygen concentration inside the cover is substantially the same as an oxygen concentration outside of the cover. 24. The method according to claim 23, wherein a carbon dioxide concentration inside the cover is substantially the same as a carbon dioxide concentration outside of the cover. 25. The method according to claim 1, wherein a carbon dioxide concentration inside the cover is substantially the same as a carbon dioxide concentration outside of the cover. 26. The method according to claim 1, wherein covering the entire load on a unit load device or on a skid transported by air via a cover, such that the cover separates the entire load on the unit load device or on the skid from the surrounding environment, and securing the cover in a covered position around the entire load on the unit load device or on the skid such that the cover separates the entire load on the unit load device or on the skid from the surrounding environment, comprises: positioning at least a portion of the cover on the unit load device or skid and positioning the entire load on the cover such that the at least the portion of the cover is between the unit load device or skid and the entire load; andpositioning a remaining portion of the cover and securing the cover, such that the cover is in a covered position around the entire load on the unit load device or on the skid such that the cover separates the entire load on the unit load device or on the skid from the surrounding environment.
