Aluminium foil does not conduct heat, so it will keep the coolness of the item within it's cover without drawing any heat from the outside elements.
For this to be efficiant you will need to completely wrape the item in alunimium foil.

Aluminum foil DOES conduct heat.
Answer
Aluminum absolutely does conduct heat. If it did not conduct heat, your hand would not warm the soda in the can.
The reason it works a little is because when you crumple foil around a can, little pockets of Air are caught in between the layers. This air is what insulates the can.
This is why bubble wrap works so well to keep thing cool.

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.
Things do not conduct cold, they conduct heat. Being a metal aluminum foil is both a good conductor of heat and electricity.
Plastic wrap I tried it myself
no because aluminum foil is a metal

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

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 keeps food colder because it doesn't let air in.
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.
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).
