Most 'tin' foil these days is aluminium. And due to the oxide coating
it's a right pain to solder to. It is posible to solder to aluminium with
normal solder and flux (I have done it) -- the trick is to put a drop of
oil on the aluminium, then scrape the surface under the oil and quickly
tin it with a hot iron and solder. Most of the time it will tin. Once
it's tinend it's easy to solder a wire (or whatever) to the aluminium.
But I wouldn't fancy trying to do that with 'tin foil'
