i think its like everything else. No high temperatures,no low. i have mines in the same place, my closet. i used them eventually.
I would store it just like any other film in a cool, dark place. I currently keep my extra film in a cupboard in my living room. It's sealed, so as long as it doesn't get hot it should be ok.
Just keep it at a cool place, I kept mine in a basement and they work fine.

The film has an expiration date.It can be stored for around two years.The film pack explains under what circumstances you should store the film.
