How to make your own moisture absorbing packets

Create homemade desiccant packets to absorb moisture from stored foods, vitamins, plant seeds, documents and other areas where high humidity is a concern. Make your own moisture absorbing packets using silica gel, a non-toxic product that is approved for general use. Make silica gel packets sized to fit small food containers or huge drums, depending on the amount of product you are protecting. Silica gel works best at room temperatures of 21 to 32 degrees C (70F to 90F).

    Small silica gel pouches

  1. 1

    Weigh the measuring container that you plan to use to weigh the loose silica gel on kitchen scales. The amount of moisture absorbing silica gel needed for each location is based on the volume of the surrounding air, the type of material to be protected, moisture surrounding the material, time frame for storage and atmospheric conditions. For household uses, 30 g (1 oz) of silica gel will protect an average of 27 litres (6 gallons) or 23,000 cubic cm (1,400 cubic inches).

  2. 2

    Pour the desired amount of loose silica gel into the measuring container. Note the increase in weight measurement on the scale to determine when to stop pouring in the silica gel. Loose silica gel is available in the floral aisle of most arts and crafts shops.

  3. 3

    Open a tea bag and remove the tea. Save the tea to use in a tea strainer. Fill the tea bag with the desired amount of silica gel. Staple the tea bag closed.

    Medium silica gel pouches

  1. 1

    Spread a coffee filter open on a flat surface. Measure the desired amount of loose silica gel.

  2. 2

    Transfer the loose silica gel from the measurement container to the centre of the coffee filter.

  3. 3

    Gather the sides of the filter up and around the loose silica gel. Secure the coffee filter closed with a rubber band.

    Large silica gel packets

  1. 1

    Cut a section of a closed-toe nylon stocking or tights leg to the desired size for the moisture absorbing packet. Include the foot section of the stocking in the measurement.

  2. 2

    Measure and pour the desired amount of silica gel into the top of the stocking leg, down to the sealed toe section.

  3. 3

    Wrap a rubber band around the stocking above the silica gel to seal.
