How to freeze open 120 film

I do not freeze film after the original package has been opened. There is plenty of space in my refrigeration for the film in ZipLok bags.

Did you request a hand check? I couldn't be bothered. Just run it through the machine. It won't hurt it...unless you're carrying around high speed film, of course. Then hand inspection is the way to go.

This was in a country where every piece of luggage (including carry on) had to be scanned by the larger machines usually reserved for checked luggage. This was just to enter the airport. Then you had to go through another round on the smaller machines to get thru security.

Then there was X ray at hotels too.

Counting up to 3-4 domestic flights between the international legs, hand check was a must.

Reply I received from Canadian Air Transport Security Authority (CATSA):

"We recommend that you put undeveloped film and cameras containing undeveloped film in your carry-on baggage or take undeveloped film with you to the checkpoint and ask the screener to conduct a hand inspection."

Just like a politician, my question if the scanners are film safe went unanswered...

Polyethylene baggies do not provide sufficient protection for film. Note that Kodak and Fuji do not pack their film in poly bags. Instead for 35 mm they use thick canisters with tightly fitting caps. For 120-size film and sheet film they use a substantial multilayered sealed barrier wrap. If the less expensive poly worked they would use it. Instead they use the much more costly barrier material. Why? Because it is necessary is film degradation is to be kept to a minimum.
