Abstract

A water vapor adsorption and water retaining composition containing particulate calcium chloride and cellulose fiber in a flexible container having a side of spun-bonded polyethylene heat sealed to a side of extrusion coated polyethylene on polyester. The foregoing composition can also contain clay.

Claims (24)

1. A water vapor adsorption and water retaining composition comprising particulate calcium chloride and particulate cellulose fiber, wherein said calcium chloride is present by weight in an amount of between about 5% and 90%, wherein said cellulose fiber is present in an amount of between about 20% and 95%, and wherein said calcium chloride is of a size of between about 0.6 mm and 4.7 mm.

2. A composition as set forth in claim 1 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

3. A composition as set forth in claim 1 wherein said calcium chloride is present by weight in an amount of about 46% and said cellulose fiber is present in an amount of about 54%.

4. A composition as set forth in claim 1 wherein said calcium chloride is present by weight in an amount of between about 15% and 75% and wherein said cellulose fiber is present in an amount of between about 30% and 80%.

5. A composition as set forth in claim 4 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

6. A composition as set forth in claim 1 wherein said calcium chloride is present by weight in an amount of between about 35% and 55% and wherein said cellulose fiber is present in an amount of between about 50% and 70%.

7. A composition as set forth in claim 6 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

8. A water vapor adsorption and water retaining composition consisting essentially of particulate calcium chloride and particulate cellulose fiber, wherein said composition is in a water vapor permeable container comprising a flexible container having a side of spun-bonded polyethylene and a side of extrusion coated polyethylene on polyester wherein the side of extrusion coated polyethylene is on the inside of the container.

9. A water vapor adsorption and water retaining composition consisting essentially of particulate calcium chloride, particulate cellulose fiber and clay in a water vapor permeable container, wherein said composition is in a water vapor permeable container comprising a flexible container having a side of spun-bonded polyethylene and a side of extrusion coated polyethylene on polyester, wherein the side of extrusion coated polyethylene is on the inside of the container.

10. A water vapor permeable container containing a water vapor adsorbing and liquid water retaining composition comprising particulate calcium chloride and particulate cellulose fiber, wherein said calcium chloride is present by weight in an amount of between about 5% and 90% and wherein said cellulose fiber is present in an amount of between about 20% and 95%, and wherein said calcium chloride is of a size of between about 0.6 mm and 4.7 mm.

11. A water vapor permeable container as set forth in claim 10 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

12. A water vapor permeable container as set forth in claim 10 wherein said calcium chloride is present by weight in an amount of between about 15% and 75% and wherein said cellulose fiber is present in an amount of between about 30% and 80% and wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

13. A water vapor permeable container as set forth in claim 10 wherein said calcium chloride is present by weight in an amount of about 46% and said cellulose fiber is present in an amount of about 54%.

14. The vapor permeable container of claim 10 wherein said water vapor permeable container comprises a flexible container having a side of spun-bonded polyethylene and a side of extrusion coated polyethylene on polyester, wherein the side of extrusion coated polyethylene is on the inside of the container.

15. A water vapor permeable container as set forth in claim 10 wherein said calcium chloride is present by weight in an amount of between about 35% and 55% and wherein said cellulose fiber is present in an amount of between about 50% and 70%.

16. A water vapor permeable container as set forth in claim 15 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

17. A water vapor permeable container containing a water vapor adsorbing and liquid water retaining composition consisting essentially of particulate calcium chloride and particulate cellulose fiber in a water vapor permeable container wherein said water vapor permeable container comprises a flexible container having a side of spun-bonded polyethylene and a side of extrusion coated polyethylene on polyester, wherein the extrusion coated polyethylene is on the inside of said container.

18. A water vapor permeable container as set forth in claim 17 wherein said calcium chloride is present by weight in an amount of about 46% and said cellulose fiber is present in an amount of about 54%.

19. A water vapor permeable container as set forth in claim 17 wherein said calcium chloride is present by weight in an amount of between about 5% and 90% and wherein said cellulose fiber is present in an amount of between about 20% and 95%.

20. A water vapor permeable container as set forth in claim 19 wherein said calcium chloride is of a size of between about 0.6 mm and 4.7 mm and wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

21. A water vapor permeable container as set forth in claim 17 wherein said calcium chloride is present by weight in an amount of between about 15% and 75% and wherein said cellulose fiber is present in an amount of between about 30% and 80%.

22. A water vapor permeable container as set forth in claim 21 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.

23. A water vapor permeable container as set forth in claim 17 wherein said calcium chloride is present by weight in an amount of between about 35% and 55% and wherein said cellulose fiber is present in an amount of between about 50% and 70%.

24. A water vapor permeable container as set forth in claim 23 wherein said cellulose fiber is of a size of between about 0.6 mm and 2 mm.
