With continuous innovation of the processing technology of the reconstituted tobacco and the cut stems, the quality of the reconstituted tobacco and the cut stems of the tobacco is improved to a great extent, and the application range and the application proportion of the reconstituted tobacco and the cut stems of the tobacco in cigarette products are increased day by day. Nevertheless, each cigarette industry enterprise still has a large amount of tobacco stalk raw materials to be scrapped and burned without effective utilization, which not only pollutes the environment, but also causes waste of tobacco resources. Resource development and application of tobacco stems become one of the key research directions of tobacco science and technology workers.
At present, the resource development application of the tobacco stems in the coated white cardboard is relatively reported, for example, patent CN102127878A discloses a cigarette packet cardboard, which comprises a core layer, a surface layer and a back layer, wherein the surface layer and the back layer of the cardboard are mixed fiber pulp paper containing tobacco fibers and bast fibers, and the mixed fiber pulp comprises 6-30% by weight of tobacco fiber pulp, 5-25% by weight of bast fiber pulp, 0-25% by weight of bleached needle pulp and 40-70% by weight of bleached broad leaf pulp. Patent CN110916238A provides a tobacco stem pretreatment method for a high-speed paper machine and a white cardboard for the tobacco, the method comprises the steps of filter pressing treatment, after three times of plate frame filter pressing, organic matters in the tobacco stems are removed, the tobacco stems can be put into the high-speed paper machine, and the organic matters in the tobacco stems are more thoroughly removed by crushing the tobacco stems into powder and then carrying out a plurality of times of plate frame filter pretreatment. Patent CN106283929A discloses a coated white cardboard containing tobacco stems and/or tobacco leaves, which comprises a raw paper layer, wherein the raw paper layer comprises a surface paper layer, a core paper layer and a bottom paper layer which are sequentially stacked from top to bottom, and an optional liner paper layer located between the surface paper layer and the core paper layer, and at least one of the surface paper layer, the core paper layer, the bottom paper layer and the liner paper layer contains tobacco stems and/or tobacco leaves. Patent CN109082928B discloses a tobacco stem coated white cardboard and a preparation method and application thereof, and the preparation steps are as follows: taking tobacco stem powder with the particle size of 1-120 mu m, adding water to prepare suspension, leaching and/or filter pressing the suspension, coating cationic starch, mixing with paper pulp, and then preparing the tobacco stem coated ivory board after pulp distribution, water filtration, squeezing dehydration, drying and coating.
