In barrier pack systems, the propellant is physically separated from the product concentrate. The propellant pressure on the outside of the barrier serves only to push the contents from the container. In the piston type system, a polyethylene piston is fitted into the container.
This permits the use of low-mass propellant tanks, resulting in a high mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber.
