"Tobacco leaf, being a biological material, is likely to spoil whenever conditions exist that encourage the onset of
mold and decomposition. When tobacco is being packaged and stored in that package, it is likely that there are
conditions for the tobacco that must be met in order for the tobacco not to spoil. The authors have identified some of the
factors known to influence the degree of spoilage in stored tobacco as being: maturity and cure of the tobacco; moisture
content of the tobacco (11); density of tobacco in the package; and the temperature, relative humidity and
movement of the air within the storage environment around the package. In order to minimize spoilage, it is necessary to know the
range of values permissible within each of these factors." The Tobacco Science Journal
