Without some water present, gelatin and acetate film would contract and become so brittle that they might crack when handled. The amount of water present in the film is determined by the relative humidity of the storage environment. Boss men damp proof cabinets with adjustable humidity governs how much water remains in the film after the equilibrium is attained.Established humidity control with high end technical research & development provides the best storage environment for microfilms and many other data.
