The coolant material load temperature, quantity, latent heat, and sensible heat will help determine the amount of heat the parcel can absorb while maintaining the desired control temperature. Combining the attributes from the insulator and coolant will allow analysis of expected duration of the insulated shipping container system.
A heat rock is the common name for a type of heating source in enclosures for cold-blooded animals to supply heat, in the form of a false novelty rock plugged into an electrical socket.

Self-heating food packaging is active packaging with the ability to heat food contents without external heat sources or power, usually using an exothermic chemical reaction. Packets can also be self-cooling. These packages are useful for military operations, during natural disasters, or whenever conventional cooking is not available.
Heating packs can also be made by filling a container with a material that has a high specific heat capacity, which then gradually releases the heat over time. A hot water bottle is the most familiar example of this type of heating pad.
To heat a meal, the bag is first torn open, and a sealed food pouch is placed inside. About 1 US fluid ounce (30 mL) of water is then added to the bag, using the line printed on the bag as a marker.
