yes it is because it traps the coolness inside.
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
Insulator or conductor depending on the circumstances. Aluminum foil conducts heat, but it cuts off air flow and reduces evaporation of fluids. Aluminum foil reflects and thus minimizes radiation transmission. With foods it is more useful as an insulator. It also acts as an insulator on windows. But, aluminum is definitely a good heat conductor.
What we usually refer to as tin foil is almost always aluminum foil. Aluminum is a very good conductor of heat, and aluminum foil makes a very poor insulator. The exception might be in the case of radiant energy, which it reflects well, and even better when it is polished.
Aluminum foil can be use as both insulator and conductor. It can wrap and trap air inside cause thermal insulating effect but in other hand, aluminum itself is a conductor for evenly distribution of heat throughout the food. Aspect of substance fabricated is different from an insulation conduction aspect of a substance.
Foil is considered to be a good insulator since it has the ability to reflect radiation. However, aluminium foil is commonly used as a conductor and not an insulator.

stira foam is a better insulator because it will keep it warm
It actually isn't a good insulator. Tin foil and aluminum are good conductors, not insulators.

yes
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
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.
Aluminum foil.
What is floil? Do you mean aluminum foil? If so, metals conduct heat fairly well.

It would definitely have to be plastic wrap because plastic wrap is an insulator, which aluminum is not.
