How it Works
The patented TRUETECH™ Self-Heating Technology is a simple combination of food grade iron and magnesium powder, salt, and water. When the contents of the water pouch are poured over the heater pad, the Food Heater releases enough heat to warm-up a pre-cooked meal 100 degrees Fahrenheit in approximately 10 minutes.
Heating any of our self-heating meals is easy.
- First tear open the heater bag.
- Place the meal in the bag against the heater pad.
- Pour the provided salt water pouch into the bag to start the heater.
- Fold the opening over and use the tape on the bag to keep it closed.
- Place the meal in the heater bag on a heat-safe surface.
Heating any of our self-heating meals is easy.
Spent heaters are biodegradable and easily disposed of as ordinary household trash. There are no toxic materials.
Cafe2Go Self-Heating Beverage Kits heat much the same way.
The patented TRUETECH™ Self-Heating Technology was introduced for use as the Field Ration Heater (FRH) by the U.S. Armed Forces in 1990 to heat Meals, Ready-to-Eat (MREs) for soldiers in the field. We’ve heated nearly 2 Billion MREs since then.

Our self-heating technology has been written about on numerous occasions. An excerpt from a high school chemistry text explanation is available, as is a more in-depth explanation from a 1992 ChemMaters Magazine article.
