Container for kind of foil (3)
I believe the answer is:
tin
I believe this clue is a double definition.
'container' is the first definition.
(I know that tin is a type of container)
'kind of foil' is the second definition.
(I've seen this in another clue)
'for' acts as a link.
(Other definitions for tin that I've seen before include "Silver-white element often used in food containers" , "loaf of bread" , "Silver-white metal, used to make cans" , "A silvery-white metal often in cans" , "With copper, makes bronze" .)
