Abstract
Humidity control devices for consumer products and methods for making the same. In particular, a humidity control device may contain a humidity control agent for controlling the relative humidity (RH) within a packaged consumer product, such as a food, pharmaceutical, herb, or any other suitable consumer product. In some embodiments, the humidity control device may be attached to, or integrated with, the product packaging. For example, the device may be fixedly or removably adhered to an inside wall of a product package. In some embodiments, the device may be constructed or formed on the product packaging material, such that the device is an integral part of the product packaging material.

16. A method of making a humidity control device for controlling headspace relative humidity in a consumer product package, the method comprising:
-
obtaining a base material comprising a wall of the product package; obtaining a humidity control agent; extruding a quantity of humidity control agent onto a surface of the base material such that a portion of the surface remains exposed and forms a perimeter around the extruded quantity of humidity control agent; obtaining a permeable material permeable to water vapor but impermeable to the humidity control agent; and arranging the permeable material over the extruded quantity of humidity control agent and the base material, such that the permeable material contacts the humidity control material and the exposed perimeter of base material. - View Dependent Claims (17, 18, 19, 20)
