Self-heating food packaging

Self-heating food packaging (SHFP) is active packaging with the ability to heat food contents without external heat sources or power. Packets typically use an exothermic chemical reaction. Other types of active packaging are self-cooling food packaging and radio-frequency identification (RFID). Packages like these are typically used by the military during operations when it is unsafe to have a fire to cook. Bananas, meat pastes, and many other foods are examples of foods that can be stored this way.


Current research focuses on cost reduction using reactions without odor or fumes. One heat source in development uses air-activation reactions that utilize oxidation of common metals like iron or zinc. Another uses solid fuel energy storage technology. The heating element contains aluminum and silica, two benign materials, which in an intimately mixed powdered state can undergo a chemical reaction to give off a large amount of heat. The small heater unit is formulated to give high utilization of the chemical energy content and generates 720 calories of heat per gram.
