to keep them together!!
Between Saran Wrap and foil, I would choose foil. But the best thing to use are freezer bags.
Plastic wrap. Foil makes it hot.
saran wrap is better
It's commonly called "tin foil" (originally it was made of tin) but it is actually aluminium foil, rolled to a thickness of (typically) less than 0.02 mm.
Aluminium foil or plastic wrap insulate the heat of the wrapped up material.
aluminum foil
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.

Simple glad-wrap or aluminum foil should do the job :)
Foil is typically used for hair highlighting as it provides more even and intense color results by trapping heat. Saran wrap can be used for a balayage technique or when a less intense color result is desired as it does not trap heat as effectively as foil. Ultimately, the choice between foil and saran wrap depends on the desired hair coloring technique and result.
only when baking
You wrap food in foil and seal all the edges before cooking it.
