Abstract: In order to verify the applicability of the storage technology of carton packing sheet tobacco non-lined plastic bag in large-scale storage of tobacco raw material warehouse, the appearance quality, chemical composition and sensory quality were measured by selecting six grades of tobacco leaves in four production areas and adopting the comparison storage of non-lined bags and lining bags. The results showed that after 18 months of storage, compared with the tobacco with inner lining bag, the smoke without inner lining bag had a lighter color change, better chemical composition and better sensory quality. It provided the basis for improving the curing quality and optimizing the store storage technology.
