What are the factors that cause the deformation of industrial paper tube

1、 Unreasonable design of box size of paper tube

In the case of the same size, the height has a greater impact on the compressive strength of the empty box. When the circumference of the four sides of the paper tube is unchanged, the compressive strength decreases by about 20% with the increase of the height of the paper tube.



2、 Poor bonding strength

Judge whether the bonding is good. As long as the bonding surface is torn by hand, if the original paper surface is found to be stripped, it indicates that the paper is well bonded; If the paper fiber at the bonding point of the paper peak is found to be free of tearing or white powder, it indicates that it is false adhesion, which will cause low compressive strength and affect the whole strength. The adhesive strength is related to the grade of paper, the preparation of adhesive, manufacturing equipment and process operation.



3、 Unreasonable printing design

Printing will cause some damage to the paper tube. The pressure and the bearing area are the main factors affecting the compressive strength of the paper tube.


Of course, we should also pay attention to it when using it. Because the paper tube has water absorption, how to use it in a humid environment will be affected by moisture and deformation, and will be seriously moldy. Therefore, we should pay attention to it when using it.
