Many decades (50's,60's) ago some brands of 120 film came in metal or plastic cans as a given, then cameras such as the Rolleiflex, Blad, Bronica became very popular with Wedding and other Pro photographers and the usage of 120 film went way up. In other words, 120 film went from an amatuer film to a much used "pro" film. Most Pro's don't want to pay for waste material, so Kodak, Fuji, Agfa, Ilford started packaging some of their films in multi roll packs and dropping the cans and even boxes. Some of the European films kept their cans as they were marketed more to the casual photographer. I have a few of the Fuji cans and used them on a regular basis. I even have a few of the metal Agfa cans for 120 and 127 size but I don't actually use them as they are Antiques. RandyB
