Foil classified in this heading is obtained by rolling, hammering or electrolysis. It is in very thin sheets (in any case, not exceeding 0.15 mm in thickness). The thinnest folls, used for imitation ilding, etc., are very flimsy; they are generally interleaved with sheets of paper and put up in fooklet form.
