Film is like meat or produce. It goes bad. Analog vinyl records keep on the shelf forever, film does not.
Freeze it, go ahead! It still goes bad. Gradually, but it goes bad. Radiation you know. So, on dealers shelves and in your freezer, film is decaying. And what is not sold is returned to EK. Oh my, that is a B**ch! That eats into profits!
So, here we are with a perishable product that is produced by the "ton" and then has to face a failing market. Go ahead, hoard. Eventually, it will go bad, fast film before slow film, but bad. It may take 1 year, 10 years or 20 years, that depends on your freezer temp or refrigerator temp but it will go bad. I have some slow film that is still good at room temp since the 70s. but I have some 90s film frozen that is bad now, less than 20 years later.
