Abstract

A humidity control system includes a humectant material, an oxygen absorbing composition, and a package housing the humectant material and the oxygen absorbing composition.

Claims

1. A humidity control system comprising:

a humectant material;

an oxygen absorbing composition; and

a package housing the humectant material and the oxygen absorbing composition.

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, further comprising a coating layer between the package and the humectant material and the oxygen absorbing composition.

4. The humidity control system of claim 3, wherein the coating comprises a microporous coating.

5. The humidity control system of claim 4, wherein the coating comprises polyethylene, oriented polystyrene, a porous polyethylene resin, polyurethane, a polyether block amide, and/or a polymeric mixture comprising a hydrophilic monomer.
