Plastic!!!!!!!!!! Aluminum recycles, but most plastics do not.

aluminum foil i think
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.
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).
aluminunm foil
ice will melt faster wrapped in aluminum foil and plastic wrap when you put it outside
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.
~Ceppwo The purpose of plastic wrap and aluminum foil is for food, it helps the food to stay good, without the plastic wrap and aluminum foil, it would be harder for us to keep it good, and with out it, the food would mold faster . . . so there's your answer:)
I think it is aluminum because its metal and bugs can go threw plastic 0_o
Aluminium foil or plastic wrap insulate the heat of the wrapped up material.
