烟用无铝内衬纸成型度的影响因素研究

The Factors Influencing Forming Degree of Aluminum Free Inner Lining Paper for Cigarette Packaging

研究了填料、浆料种类、打浆度、表面浸胶、涂布、压光、纸张水分等多种因素对烟用无铝内衬纸成型度的影响。结果表明,纸张水分对成型度影响较显著,增加压光前纸张水分,使压光后纸张残留的水分较多,纸张的成型度较低;此外,添加粒度较小的填料、增加阔叶木浆的用量、原纸经过适当压光、用合适的涂料进行单面涂布也有利于降低成型度。

Abstract ： The effects of filler type, pulp type, beating degree of the pulp, surface sizing, coating, calendaring, moisture on forming degree of aluminum free inner lining paper for cigarette packaging were investigated in this paper. The results showed that moisture had significant effect on forming degree. When the moisture of paper sample increased before calendaring, residual moisture in the calendared paper sample was relatively higher, which caused lower forming degree. The forming degree decreased significantly if the paper was used in damp condition. What＇s more, using filler with small particle size, increasing usage of hardwoods, applying appropriate calendaring treatment, one side coating with appropriate formula were all beneficial to the forming degree.
