How do carton manufacturers solve the problem of carton collapse

In the production process will encounter a headache, that is, for the collapse of the box and the adhesion of the box machine is not strong, Haixin packaging summarized the solution is to improve the cardboard material, improve the compressive strength and moisture-proof performance, so as to reduce the collapse rate. In addition, the factory needs to improve the bonding strength, increase the solid content of starch paste, and improve the hardness of cardboard by reducing the amount of glue to solve the problem of sticking box machine.

How to deal with the problem of the box sticking machine is not strong, the production and use of the following points should pay attention to:

1, to control the use of base paper

Check the sizing of corrugated paper and the water absorption index of the surface of the base paper. If the surface of the base paper is poor in sizing, the water absorption will be high, and it is easy to be affected by the low temperature and wet environment of the hand cold storage, resulting in moisture return, softening, and reduced compressive strength of finishing.

2, the production of cardboard to control the moisture content of cardboard

The moisture content of the cardboard should not be too much, because the moisture is large, the hardness of the cardboard is low, and the edge pressure index of the cardboard is affected. In the process of cardboard processing, the amount of glue on the single-sided machine and double-sided machine can not be too large. Once the amount of glue is large, the corrugated shape of the cardboard will be deformed, and the shape of the corrugated directly affects the side pressure of the cardboard, and the side pressure is reduced, the compressive strength is also reduced.

3, the adhesion strength of cardboard should be large

Adhesive strength is the adhesive force between corrugated paper and inner paper and face paper. If there is false sticking of the cardboard, after the pressure, the face paper or the inner paper will be separated from the corrugated paper, then the compressive strength will plummet.

4, the gap pressure control in the production process should be moderate

In particular, it is necessary to pay attention to the gap pressure of the paste box machine can not be too small, and the gap pressure of the sun wheel on the double-sided machine and the die-cutting machine should be controlled within a reasonable range to avoid crushing the corrugated shape and affecting the compressive strength of the cardboard.

5, the use of water spraying agent, waterproof gloss oil to solve the problem of surface waterproof and moisture-proof.
