| Abstract: |
| The physical properties of white cardboard for cigarette packaging have a great influence on its application effect, and the physical properties of different white cardboard are quite different, which needs to be analyzed from the microscopic point of view to provide a certain theoretical basis for the quality control of tobacco paper. Fiber analyzer, paper fiber measuring instrument and paper property testing equipment were used to analyze the fiber morphology, type and physical properties of each layer of white cardboard for cigarette packaging samples. The difference of physical properties of different white cardboard was studied from the aspect of fiber characteristics. The content of coniferous wood pulp in the white cardboard and the fiber length of the core layer were one of the main reasons for the difference of the physical properties. With the increase of the two factors, the physical strength of the sample increased. The microscopic reasons for the difference of physical properties of white cardboard for tobacco packaging are studied, and its formation mechanism is preliminarily discussed, providing a theoretical support for the quality control and application of tobacco paper. |
