How long does a 35mm film roll last undeveloped? Would a digital Memory Card last longer?

I was wondering about a roll of film I found in the garage that has been there for some time. It has been stored in tuperware but it still gets down below Zero in the winters and really humid inthe summers. I can only estimate the age of the film to around 5 years old cause thats when we bought our house. How long is film good for? If this were a digital memery card from a modern camera would it be better adapted to survive this condition? How long would a memory card be good for?|||The film will probably be OK, but pictures from it might not be as crisp as you would get from a new roll. Very high humidity could damage the film, and normal background radiation from cosmic rays and other natural sources will cause some clouding, although you would need to use a strong magnifying glass to see this. Unless the film was wet, it should be OK for prints 8x10 and smaller.





New digital memory cards should last longer because they are not affected by the heat and humidity we would see in a garage, and because background radiation would have far less effect. In theory, a digital memory card should last a very long time; however, we will not know this for sure until they have been around for a very long time.|||I would say that the roll of film is garbage, even if it wasn't exposed to below zero temperatures, I think it would of had to be developed by now. Depending on usage, I would say a memory card could last decades, even in extreme temperatures. I've never had a problem with mine and I have some that are almost 10 years old.
