Abstract:The tobacco stem material was pretreated with biomimetic system, subsequently chemi-mechanical pulping and bleaching were carried out, the bleaching and paper making technologies of tobacco stem were also researched. The results showed that the tobacco sheet had appropriate physical properties when tobacco stem chemi-mechanical pulp was bleached with peroxide under the conditions of H2O2 dosge 8%，retention time 120 min，temperature 80℃;on the other hand the tobacco sheet had appropriate brightness when H2O2 dosage was 8%，retention time was 90 min，temperature was 70℃. A new type cigar wrapping paper was manufactured with the furnish containing 80% tobacco stem chemi-mechanical pulp and 20% wood pulp， the paper with tensile strength 1.09 kN/m permeability 9.05 μm/（Pa·s）and elongation 1.42% could meet the requirement of cigar wrapping paper.
