Humidity control system
A humidity control system includes a humectant material, an oxygen absorbing composition, and a package housing the humectant material and the oxygen absorbing composition.
1. A humidity control system comprising:
a humectant material comprising:
a viscous miscible glycerol; and
water;
an oxygen absorbing composition;
a package housing the humectant material and the oxygen absorbing composition; and
a coating coated on an inner surface of the package and between the package and the humectant material and the oxygen absorbing composition, the coating comprising polyethylene, oriented polystyrene, a porous polyethylene resin, polyurethane, a polyether block amide, and/or a polymeric mixture comprising a hydrophilic monomer.
2. The humidity control system of claim 1 , wherein the package defines a single cavity that houses the humectant material and the oxygen absorbing composition.
3. The humidity control system of claim 1 , wherein the coating has a thickness from between about 0.001 inch and about 0.01 inch.
4. The humidity control system of claim 1 , wherein the package comprises kraft paper having a basis weight of 30 lbs/msi.
5. The humidity control system of claim 1 , wherein the package comprises an elastomeric polymer.
6. The humidity control system of claim 1 , wherein the oxygen absorbing composition comprises:
a fatty oil; and
a transition metal enhancer.
7. The humidity control system of claim 6 , wherein the transition metal enhancer comprises chromium, manganese, cobalt, iron, copper, and/or zinc.
8. The humidity control system of claim 6 , wherein the fatty oil comprises an unsaturated fatty acid.
9. The humidity control system of claim 8 , wherein the unsaturated fatty acid comprises an oleic acid and/or a linoleic acid.
10. The humidity control system of claim 6 , wherein the fatty oil comprises a vegetable oil comprising triglycerides.
11. The humidity control system of claim 10 , wherein the vegetable oil comprises linseed oil, soybean oil, and/or flaxseed oil.
12. The humidity control system of claim 1 , wherein the humectant material further comprises a gelling agent.
13. The humidity control system of claim 12 , wherein the gelling agent comprises gelatin, xanthan, alginate, and/or pectin.
14. The humidity control system of claim 1 , further comprising lemon oil.
15. The humidity control system of claim 1 , further comprising a humidity indicating card affixed to a surface of the package.
16. The humidity control system of claim 1 , wherein the coating comprises the polyether block amide.
