How to deal with the problem of the carton packaging machine cohesive and the carton collapsed?
To control the use of the base paper. Check the sizing of corrugated paper and the effect of water absorption on the surface 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 environment of the cold storage, which causes the carton to regain moisture, soften, and reduce the compressive strength of the finishing.
Control the moisture content of the board when producing the board. The moisture content of the cardboard should not be too much, because the moisture of the cardboard 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 cardboard is large. The bond strength is the adhesion of corrugated paper to backing paper and 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.
