The two functions I have put together are the plastic food tray bag and the portable food saver. In space they usually use one food bag preserver for one type of food, but with my food tray you can put more than one food type. I also added the portable food saver so it can save more space. In space they use this big machine which dehydrates and rehydrates the food, but with the portable food saver it takes up less space and can be easy on astronauts. It is also easily managed.
