How to deal with the problem that the glue box is not sticky and the carton collapses
To control the use of the base paper, check the sizing of the corrugated paper, and the water absorption index of the base paper. If the surface of the base paper is poorly smeared, the water absorption will be high, and it is easy to cold and humid carton gluing machine environment of the cold storage, which causes the carton to regain moisture, soften, and reduce the compressive strength of the finishing.
When producing paperboard, the moisture content of the paperboard should be controlled. The moisture content of the paperboard should not be too much, because the hardness of the paperboard is low, which affects the edge pressure index of the paperboard. In the process of paperboard processing, the amount of glue on the single-sided machine and the double-sided machine can not be too large. Once the amount of sizing is large, the shape of the cardboard will be deformed, and the shape of the corrugation directly affects the side pressure of the cardboard, the side pressure is lowered, and the compressive strength of the cardboard box is also reduced.
The bonding strength of the paperboard is large, and the bonding strength is the adhesion of the corrugated paper to the inner paper and the facial tissue. If there is a cardboard false stick, the paper or the inner paper will be separated from the corrugated paper after the paper box is pressed, and the compressive strength of the paper box will drop linearly.
The gap pressure control in the production process should be moderate, especially pay attention to the gap pressure of the paste on the paste box machine should not be too small, the double-sided machine, the sun wheel clearance pressure on the die-cutting machine should be controlled within a reasonable range to avoid the corrugated pressure Crush, affecting the compressive strength of cardboard cartons.
