Re: Question on humidity tightness of film canisters

I think you’ll be okay. I had a similar thing happen this past winter when we lost power in my studio for a few days. Being on disabled means that I no longer go there every day so I had no idea. I have 300 rolls of APX100 120 in the freezer and a 300+ rolls of Reala in the fridge. After power was restored I let things get back to the cold again and did some film testing and everything was fine. 

In my travels around Europe and elsewhere I have found that the big danger to ruining elderly film is x-rays, not heat unless it is in the high 80’sF or above. When I travel again, I will be taking my lead bags to the airport to get accused of being a terrorist in the US while the Brits say ”Ho hum, oh yeah, that’s a lead bag and I suppose it’s got film in it?” Knowing what I know about x-rays now, I wish I could wear a lead bag on the plane. During my leg ordeal I had hundreds of x-rays and I know they will make me die young.

Short of welding your film into a metal box, I think the best solution is to store it in Tupperware along with a small bag of Silica Gel - perhaps no more than 30g. When / if you lose power or the film gets warm, do not open the Tupperware. Plastic bags are moderately transparent to water and gases, but Tupperware is forever. Folded over plastic bags or with Ziplok are just about useless for anything other than a shower.

hi all1!
 
I have a question on the humidity tightness of film canisters. Not waterproofness, but humidity proofness.
 
here is my situation.
Few days ago we had a case of molten ice in our fridge. Water was everywhere including around my stored films.
 
My storage methods is this.
Each film is in a cannister with a label on top and one in the bottom (place to keep notes on)
Film cannsiters are kept in tupperware like containers
All the containers are kept ina folded over plastic bag
 
So what I found when I opened the containers was moisture effects on some of the TOP labels, spoiled ink of the parmenent markers writting in particular. this was on top of the film cannisters, no signs of moisture were observed on the bottom labels nor inside the cannisters (paper labels were good).
 
Since the top labels were very close to the lid bottom I am considering the condesation possibility, since the tupperwares were left out of the fridge for a day till we sorted the issue out.
 
To cut it short. Am I to fear there has been increased humidity inside the film cannisters to affect the film itself?
I am worried cos this is a stock of hard to find (and expensive) films
 
thanks, Kostas
