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.

Famous quotes containing the word food:
“I’m the only woman reporter they have, so I get all the meat boycott stories and all the meatless food stories.... Actually, I’ve only cooked three meals in my life. The most uncomfortable place for me in the whole world is in a kitchen.”
—Theresa Brown (b. 1957)
