Apparatus and methods of packing leaf tobacco preserve the integrity of tobacco, help retain freshness and moisture content of tobacco, and also help eliminate insect infestation. A packing container for leaf tobacco includes a carton, and a flexible, non-porous bag located within the carton. The bag includes a closeable opening through which the bag receives a quantity of tightly packed leaf tobacco. The bag is configured to have air extracted therefrom and to maintain a sub-atmospheric pressure therein.
