Abstract
A self-heating product pouch has a first thin flexible material that surrounds and defines a product compartment. A second thin flexible material is coupled to an outwardly-facing surface of the first thin flexible material to define a first heater compartment that is outside, but thermally coupled to, the product compartment. A first thin porous substrate inside the first heater compartment. A granular reactant is distributed throughout the first thin porous substrate. A frangible container is inside the first heater compartment. A liquid reactant is inside the frangible container. The granular reactant and the liquid reactant are adapted to react exothermically upon contact with one another.
