Flameless Heater Pad
The pack consists of an outer foil cooking pouch and 2 inner plastic heat pads containing sachets of reactants. Add water to a freeze dried meal pouch to reconstitute it and then put it into the foil cooking pouch. Add water to the inner heat pads to initiate the reaction. The sachets in the heat pads contain mixed powdered magnesium, powdered iron and salt. When water is added to the heat bags the salt forms an electrolyte solution, the iron acts as an anode, the magnesium acts as a cathode, and the magnesium oxidises at an increased rate giving off strong heat. The product will not generate flame or sufficient heat to cause ignition.
