Aluminium foil or plastic wrap insulate the heat of the wrapped up material.
Aluminum foil is the best at keeping things hot because it reflects heat and acts as a barrier to prevent heat loss. Plastic wrap and wax paper are not as effective in retaining heat as aluminum foil.

aluminum foil is better at blocking temperature from getting out than plastic wrap. the atoms in the element aluminum are bigger and have more neutrons/electrons and protons than the elements in plastic wrap.

aluminum foil it seals the cold in alot more than plastic wrap.ans2, RIGHT answer, but reason not quite correct. The shiny aluminum will reflect all heat.And since your package is cold, the only ways it can heat up are conduction, radiation, and convection. Of which three, Aluminum foil will stop radiation and largely stop convection.
Aluminum foil is better at keeping things cold because it reflects heat and light, which helps to maintain lower temperatures. Plastic wrap does not have the same insulating properties and is more prone to tearing or losing its shape when exposed to cold temperatures.
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).
Plastic!!!!!!!!!! Aluminum recycles, but most plastics do not.
Aluminum foil is better at keeping things colder compared to plastic wrap. This is because aluminum is a better insulator and can reflect heat more effectively than plastic wrap.
For one thing, it's spelled PLASTIC WRAP and two. Aluminum foil keeps things cool, or cooler by how good it is as a insulator. It lets the temperature sort of flow through where it needs to go. And you can kind of control this by rolling the foil thicker or thinner.
The rate at which water freezes depends on the thermal conductivity of the container. Plastic is generally not very thermally conductive, whereas aluminum foil is more thermally conductive. Thus, as long as the foil is not very much thinner than the plastic, the water will freeze faster in the foil.
