A temperature modifying system for heating or cooling a product including a flexible outer container containing a product and a self-enclosed temperature-changing element is disclosed. The temperature-changing element includes a flexible pouch at least partially immersed in said product. The flexible film pouch may have two components separated by a rupturable barrier that is adapted to burst under an application of pressure allowing the two components to combine or react in an exothermic or endothermic event. The flexible film pouch may alternatively include a saturated salt solution that generates as it drops out of solution.
