When exposed to oxygen, the iron in the pouch oxidizes and makes your warmer toasty. When the iron oxidizes, it produces iron oxide, AKA: Rust! The salt works as a catalyst to speed up the process, and the carbon helps to disperse heat. The vermiculite is an insulator, keeping all the warmth in the bag. All the magic ingredients are sealed safely inside a little polypropylene bag. The polypropylene allows oxygen to permeate the ingredients whilst retaining any moisture.
