The water content, physical property and sensory of cigarette brands have been studied from the view point of the individual and inner packages. It was found that the cigarettes had absorbed the moisture from air more than 56 % of a relative humidity (RH) and lost it under RH, 56 %. The critical moisture contents for the optimum quality of cigarette maintenance were 7.7 % through 14.5 % in the range of equilibrium relative humidity (ERH) 52.2 % - 63.5 %. The ERH at the initial moisture content of 12.1 % showed 58.8 %. When cigarettes were stored in 90 % of RH and 40 deg C, the shelf life of the inner package was respectively shown 18.8 days in cellophane, 33.3 days in PET (25u), 69.8 days in OPP and 73.5 days in OPP film coated with PVDC
