What are the common problems in the mounting process of wooden packaging boxes?

1. Increase the solid content of the mounting glue and reduce the amount of glue. Because when the solid content is higher, the water contained in the glue is less, and the amount of glue applied is reduced, so that the absorption of water per unit area of the cardboard is greatly reduced, and the purpose of improving warpage can be achieved.  

2. The direction of the paper grain is correct, that is, the straight strands of the face paper and the corrugated cardboard are mounted in a "ten".  

3. The stacking method should be correct.

4. The direct way is to apply a certain amount of pressure to the severely warped cardboard to improve the cardboard.

Common problem 4: Delamination of packaged products

When the proportion of effective adhesive substances in the glue is too low and the viscosity of the glue is too low, the quality of the adhesive is not good enough, and it is easy to delaminate the packaging. There is also a small amount of glue, and it is necessary to carefully check the quality of glue and the amount of glue.
