Aluminum foil would keep a sandwich warm longer than a foam box.
Not sure I would agree with the foregoing: aluminum is a very good conductor of heat and gains (or loses) heat easily. Foam would insullate the sandwich better, minimizing any temperature changes, and therefore would keep it warm (or cold) longer.

Aluminum foil does not keep a soda pop cooler for longer periods of time since aluminum is not an insulator. Foam can wrappers do insulate and keep soda cooler for longer periods of time.
Foam cups used mainly in vending machines, are cheap to produce and are easily disposable. The foam also keeps the hot liquid warm longer and is not too hot to hold in bare hands.
the foam containers help and they also help keep coffee warm.
Aluminum is the best conductor of heat among the materials listed. Glass, plastic, and foam are poor conductors of heat in comparison to aluminum.
Some are and some aren't. Polyurethane foam is, in general, not fireproof, while aluminum-faced foam generally is.

Use two pieces of lunch meat put it in the middle and squish them together.
Foam cups are commonly used for serving hot and cold beverages like coffee, tea, and soft drinks. They provide insulation to keep drinks hot or cold longer and are convenient for take-out orders or events where reusable cups are not ideal. However, they are not environmentally friendly as they are not easily recyclable or biodegradable.
stira foam is a better insulator because it will keep it warm
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
