Self-heating food packaging
Self-heating food packaging is active packaging with the ability to heat food contents without external heat sources or power, usually using an exothermic chemical reaction. Packets can also be self-cooling. These packages are useful for military operations, during natural disasters, or whenever conventional cooking is not available. They are often used for military field rations, camping food, instant food, or other types of food intended for preparation where proper cooking facilities or methods are unavailable or less ideal.
