The filling capacity of shredded tobacco is related with its resistance to compression and its specific volume. Therefore, it is assumed that the filling capacity (FC) is constituted by three factors, that is, the elastic modulus of tobacco (E), the specific volume of leaf self of tobacco (V_M) and the relative bulkiness of tobacco shreds at a loose fill (V_p). For the purpose of representing relationships among those four variables, quantitatively, the following multiple regression formula was statistically calculated with many experimental data obtained on typical varieties of natural tobacco cultivated in Japan. (FC)=C_1+C_2+C_3V_P+C_4V_M The results obtained are as follows: (1) The influence of E on FC was greater than that of V_P or V_M, V_P and V_M had similar influence on FC. (2) The esimated precision of other regression formula using V_Q (the relative bulkiness of shreds at an initial moment of pressure generation) in place of V_P was better than that of the above-mentioned fomula using V_P. (3)Similar consequences as (1) and (2) were achieved from other calculation using E_G (the elasticity per unit dry weight), V_A (the total bulkiness at a loose fill of shreds, V_A=V_P+V_M), V_B (the total bulkiness at an initial moment of pressure generation V_B=V_Q+V_M) in place of E, V_P, V_Q and V_M. (4) In conclusion, it was confirmed that the investigation of E is indispensable to analyze FC.
