Today’s market for Kraft paper products and raw materials is becoming increasingly chaotic. Some customers in the purchase of Kraft paper is very pay attention to the physical properties of papers, such as breakage resistance, tightness, extrusion, folding resistance and so on. In fact, these physical Kraft paper properties are related to the evenness of Kraft paper.
The evenness of Kraft paper is closely related to the quality of Kraft cardboard, because the raw material of a piece of paper is fiber, and evenness is the uniformity of the fibrous tissue of the paper. The paper can be seen in the place of the bright light. Kraft paper has a good degree of evenness and will have a lot of advantages. In the printing aspect of the poor evenness of paper, the surface smoothness is relatively poor, ink absorption and tightness will be uneven, such inhomogeneity is bound to disrupt the evenness of the printing screen and reduce the quality of printed products.
Evenness is so important, but it is not easy to control when producing paper. Many factors can lead to changes in uniformity at the time of production. The lack of pulping is an important factor affecting the poor evenness of Kraft paper, and the longer the fibers, the easier it is to gather together. The lack of pulping can easily lead to fiber forming, resulting in uneven distribution of paper fibers, serious impact on the quality of paper.
