| Abstract: | A formula for the dampproof conservation period of tobacco packaging was deduced when its film thickness distribution was linear, by analyzing the moisture absorption and vapor model of the tobacco packaging. Also, the relationship was discussed between (the ratio between conservation period which film thickness distribution is linear and conservation period which film thickness distribution is uniform) and (the unevenness of film thickness). Finally, some useful results in controlling film thickness distribution were concluded. |
