Unlike the CookPak^® system, all other commercial self-heating package technologies use water rather than air to produce the heat generating reaction. Generally the water is also included in the package so that the whole system is self-contained, adding substantial weight and bulk, and requiring the user to carry out a sequence of steps to mix the water and heater material. Market penetration for these products has been very limited.

Lightweight - The special CookPak^® system heater composition and its reaction with the surrounding air produce the lightest possible weight and size for a compact, easy to carry hot meal.

Safe To Use - Safety is “Baked In” the CookPak^® system. The CookPak^® system has multiple design features to provide inherent safety. Operation is completely flameless and system temperatures are strictly regulated to within acceptable limits.

No Liquid - There is no free liquid “activator” solution to spill or leak. The heat generating chemical reaction is a solid fuel locked into a porous matrix through which air is channeled. The heater matrix is designed to direct energy to interior food-contacting surfaces and insulate the outer surfaces which are just warm to the touch.

No Gas Produced - In addition to heat, the only byproduct of the reaction is a solid oxide material that remains in the porous heater body and never sees the light of day. There is no carbon dioxide or other gasses emitted. While the heater is always separated from the food, even if the heater compartment is compromised all of the materials are GRAFS (generally recognized as food-safe). When the food is consumed the package and heater can be disposed of or recycled in the same manner as equivalent household waste.
