Dessicant Sachets

WGMC Desiccant Sachets are a simple, easy, and economical solution for the control of moisture and high relative humidity in enclosed cases and cabinets. It significantly delays or prevents corrosion and tarnishing of your valuable possessions in temporary or long-term storage. It also minimizes shrink-swell cycles in wood products.

Please keep WGMC Desiccant Sachets in their factory sealed individual plastic or foil packages until you are ready to use them. When you open the individual packages containing the WGMC Desiccant Sachets, the granular material inside the sachet will be activated. When installed in an enclosure or case, WGMC Desiccant Sachets absorb moisture from the atmosphere and stabilizes the ambient relative humidity to a near constant level.

The Action of WGMC Desiccant Sachets

Once removed from their factory sealed plastic or foil packaging and are exposed to the environment, WGMC Desiccant Sachets will activate automatically. Then, over a period of hours or days, in an atmosphere of high relative humidity, the sachets will become soft putty like to the touch alternating between feeling firm and brittle as the moisture in the air decreases. An alternating consistency is normal and proof that your WGMC Desiccant Bags are working!(if the granules in the sachets feel hard and compressed just rub them together in the sachet do not remove from the sachet, rub until you feel the granules are loose again but this is not really necessary)As WGMC Desiccant Sachets are self-rejuvenating.

The Durability of WGMC Desiccant Sachets

Extreme Conditions – Please Note

If you open one of your cases, cabinets, or boxes and notice a swollen WGMC Desiccant Sachets, this is an indication that liquid water has entered the enclosure. Check the seal of your case, cabinet, or box and repair or reseal, if necessary. Even though your WGMC Desiccant Sachets will regenerate itself when exposed to fresh air, we recommend replacing the swollen packet.  

Installation of WGMC Desiccant Sachets

Installation of WGMC Desiccant Sachets is simple and easy. Since moist air is lighter than dry air, moist air will rise to the top of an enclosure. Therefore, placing WGMC Desiccant Sachets in the upper one-third of a case, cabinet or storage box will work best. But if convenience dictates, placing a bag in the bottom of an enclosure will work too.  

WGMC Desiccant Sachets can be attached to the inside of any case, cabinet, storage box by means of hanging the sachet by it's looped label or adhesive tape, staples or thumb pins. When using staples or thumb pins, ensure that they are attached to the bag on the outer edge seam or through the label, to ensure no granules spill out from the bag. Never remove granules from the individual sachets.
