Study on the Decrease of Harmful Substance in Paper-Process Reconstituted Tobacco Sheet

Effect of wood pulp fiber and filler on the mechanical properties and harmful substance of reconstituted tobacco sheet were investigated. Experiments result showed that added lower lignin content pulp reduced phenols produced by reconstituted tobacco sheet combustion. As addition of bleached hardwood kraft pulp and precipitated calcium carbonate (PCC) increased, the amount of phenols release was dropped dramatically, but in order to ensure the normal operation of papermaking mechine, wood pulp and PCC addition should not be more than 20%. If wood pulp addition was above 20%, it had negative effect on the bulk, carbon monoxide and cigarette smoke flavor of reconstituted tobacco sheet; when PCC addition was more than 20%, it has negative effect on the normal operation of papermaking mechine.
