Why does aluminum foil keep stuff hot and cold?
Aluminum foil is air tight. It works by sealing the item from the atmosphere. There is some assistance from the reflective surface, but not much. And it works best if it is not in contact with the item being protected, as it conducts heat very well.
How does aluminum foil reflect sunlight?
In fact, many mirrors are actually a film of aluminum deposited on the back of a sheet of glass. So yes, aluminum foil does reflect 'like a mirror'. The reflectivity of most common aluminum alloys is in excess of 98%, in both the visible and infrared ranges of light.
What makes things colder aluminum foil or a plastic wrap?
speaking from experience and not from science, foil is a very good conductor of heat which means it can go from hot to cold very fast (and vise versa) whereas plastic is waterproof and will keep the cold moisture (or warm moisture) in the food and we all know that water is a poor conductor of temperature thus keeping your food colder (or hotter) for longer.
Is cloth a good insulator to keep cold things cold?

How does plastic wrap or aluminum foil keep things colder?

Which material makes a better heat insulator newspaper or aluminum foil?
Aluminum foil is a better heat insulator than newspaper. Aluminum foil reflects thermal energy, while newspaper absorbs and conducts heat. Therefore, aluminum foil will help keep heat in or out more effectively.
How can I keep water cool?

What keep things colder aluminum foil or plastic wrap?
If the object is warm to begin with, aluminium foil, as it is a metal and so will conduct the heat out into the environment. (Metals feel cold because they are good conductors and so conduct the heat out of you when you touch them). If the object is cold to begin with, plastic wrap, as it is a poor donductor and will not allow heat from the environment to enter the object easily. (Plastics feel warm because they do not conduct the heat away when you touch them).
