35mm Film Canisters

No exactly a 'film' question, but does anyone know why some canisters are air tight (Fugi Color) and some are not (Kodak TMax) ?

As far as I know they are all airtight, unless the lids are somehow too loose to fit snugly.

Fuji uses the same type of canister for all its films (lid colour may vary, and some films seem to have beige opaque canisters, but they are all of the same design). Kodak uses the same canister for all its films as well.

Do they need to be airtight? Should film be put back into airtight cannisters after they've been shot with?

If you refrigerate them or freeze them after shooting (due to delayed processing), yes, they should be in airtight containers. Otherwise, airtightness isn't important but the canisters provide physical protection to the film cartridge, which is never a bad thing.

Re-checked and you are correct. My assumption, now false, was made as a result of an alternative use of empty canisters.. Alkaseltzer rockets with my grandsons. I first tried Kodak cans since I have a ton of them. It never built sufficient pressure and just oozed and bubbled out from under the lid. Then tried a Fugi canister I had and it worked great. The boys thought was pretty cool. So it turns out it's just a matter of how tightly the lids are secured. See, I said this wasn't exactly film related.

The Kodak Cans in the last few years have a lid that was redesigned to make it easier to open. You can tell the newer design as there are little spike link ridges on theunderside of the lid. The Fuji cans have been the same design with a few minior cosmetic changes since at least the 1980 era. (the lids orignaily said "Fujifilm" in an oval, and the older ones don't have recyling symbols)

Fuji sems to have now standardised on translucent cans with translucent lids. They on one time used different coloured lids for different film lines. The 1600 ISO films also used to come in a beige or black can.

BTW, It is FUJI, not FUGI.

Thanks for catching my mental lapse.
