Me personally I would say that plastic wrap keeps things colder because it keeps things better contained than aluminum foil. See aluminum foil rips easily than plastic wrap. So I would say plastic wrap.
It depends on the thickness of the two materials, typically Foil will keep things much colder because of its very high thermal conductivity.
aluminunm foil
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 i think
aluminum foil keeps things colder.
~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:)

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.
Aluminium foil or plastic wrap insulate the heat of the wrapped up material.

reduce plastic, styrofoam ,and aluminum foil.
Things do not conduct cold, they conduct heat. Being a metal aluminum foil is both a good conductor of heat and electricity.
It would definitely have to be plastic wrap because plastic wrap is an insulator, which aluminum is not.
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).
aluminum foil
No its not. Why? Because plastic wrap doesn't connect to coldness or warmness i was to wrap something to keep it cold it would be aluminum foil doesn't conduct any heat
