What are the main problems common in paperbox production?

-
1.To control the use of the base paper
We should check the sizing of corrugated paper. If the surface of the base paper is poorly sized. Its water absorption will be high, and this will cause the carton to regain.

2. To control the moisture content of the cardboard
The moisture content of the cardboard should not be excessive. Because the moisture is large and the hardness of the cardboard is low, which affects the edge pressure index of the cardboard.

3. Cardboard should have a strong bond strength
If the strength of the cardboard is not great, the compressive strength of the carton will plummet.
