1.paper tube Paper moisture content: Different paper moisture contents can also cause changes in paper length. The higher the moisture content of the paper, the more severe the shrinkage of the paper after printing.

2. Under the same tension, the larger the paper used for printing (thicker paper), the more severe the shrinkage of the paper after printing. However, the factor of high moisture content in thick paper should also be considered. Generally, the tension should be increased for thick paper.

3. The tension of the paper tube refers to the stretching force exerted by the paper feeding system on the paper during the printing process. In professional paper tube factories, excessive tension during the printing process can elongate the paper. After printing, the tension is eliminated, and the paper will inevitably retract, resulting in the problem of short duration in page matching, which affects page matching.

In addition, the paper tube has strong cold resistance, good fluidity under zero temperature conditions, and does not undergo gelation. Rapid evaporation of water, low shrinkage rate, and minimal deformation; Good storage stability, no delamination or deterioration when stored at room temperature for more than three months.
