Corn Bags have become more popular over the past few years, partly because of the easy of finding the filler - dried field corn sometimes called Deer corn. This type of corn is generally used as animal feed or in food production. Some people have been none to use pop corn whoever that may lead to the corn "popping" if it is left in the microwave to long.
Because corn is more readily available it has the advantage of usually being less expensive that other types of heating pads. They can be used as a cold pack by putting in a plastic bag and then into the freezer over night. People who use it often as a cold pack may have two one for a hot pack and one in the freezer for cold. However the same bag can be used for hot or cold.
