Abstract
A self-heating assembly includes a product tray for containing a product to be heated and a heater tray outside the product tray and configured relative to the product tray to define a reaction space between the heater tray and the product tray. A frangible container made of a shrink film material is inside the reaction space. The frangible container contains a first reactant that is a liquid. A second reactant is outside the frangible container. The first and second reactants are configured to react exothermically upon contact with each other.
