Cold storage of film

The life expectancy of a film can be lengthened by lowering the temperature under which the film is stored. In 1889, Savante Arrhenius showed that the rate constant of a reaction was dependant upon temperature.

As temperatures drop, the movement of molecules slows down and lowers the rate at which chemical reactions can take place, reducing the rate of the decomposition reaction. In practical terms the rate approximately halves for every 5°C drop in temperature and conversely doubles for a 5°C increase.

This chapter contains pages on Cold storage, Acclimatisation and Dessicants.
