Thanks. I am trying to get to the bottom of this "light-tightness" or otherwise.PE has posted that the black cans with grey tops that Kodak uses are not light tight.
Why would you need/want a light tight film canister?
I always considered myself pretty risk adverse, but since I haven't had a problem with a film cassette in nearly fifty years, I am going to go out on a limb and not worry about it. YMMV.Safety: Why would you want a seat belt or airbag in your car if you never plan to crash it?
If your film cartridge has a small flaw, a light tight container for it can be the difference between having a barely noticeable defect picked up on the film from the small exposure time it spent going from the canister to the camera and back, vs having it completely washed out due to prolonged light exposure while it sat out somewhere before/after use.

Some people tear those off and put them in the little slot on the back of their SLR, right? So this makes good sense.
Not required until someone tears the film off a spool, had to go into a changing bag to recover their film, and then puts the salvaged film into a cannister with a lid that passes light. And our school bulk loads and reuses the cannisters and students seem to delight in trying to "stretch" the bulk loads to get one more shot.Is there a requirement for them to be so?
(Special films aside.)
Light-tight film cans are handy sometimes. It's a rare occurrence, but having a light-tight place to stash an opened (in the darkroom) roll can be useful.
As a user mainly of Ilford Delta 400 2 1/4 a nice retro touch would be to return to a flavored adhesive on the sealing strip once the roll is exposed. At one time it was mint flavored.

I work in product development. Packaging may need more attention than the actual product. The labels and printing can allow or deny access to a market. The packaging must protect the product. It is a science.It must have been a really slow day around the office when they decided to change the packaging.![]()
