Abstract

The present disclosure provides an environment-friendly wrapping-free heat-not-burn naked tobacco product. The tobacco product includes, in percentage by mass, 20-60% of mixed powder, 10-40% of a porous carrier material, 15-50% of a tobacco extraction mixture, 1-10% of a particle aggregation inhibitor and 10-40% of a binder. The environment-friendly wrapping-free heat-not-burn naked tobacco product can effectively inhibit emission of harmful substances in smoke; meanwhile, a paper tube, a filter tip and a blocking piece which are required for a traditional cigarette are not needed, the naked tobacco product is utilized, the difficulty of a production process is lowered, raw materials are reduced, and the tobacco product is more environmentally friendly. According to the tobacco product with the proportion of components, the smoke amount is abundant, the fragrance is good, smoke is soft and fine, offensive firewood smell is avoided, irritation is small, the remaining taste makes people comfortable.
