Carton packaging factory will encounter a headache problem in the production process, which is the problem of sticking to the collapsed box and the glue box machine. Tianjin Machinery concludes that the solution is to improve the paperboard material, carton gluing machine improve the compressive strength and moisture resistance, and thus reduce The rate of collapse. In addition, a little factory needs to improve the bond strength, increase the solid content of the starch paste, and improve the hardness of the paperboard by reducing the amount of glue to solve the problem of sticking to the glue box.

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 wet the environment, resulting in regaining moisture, softening, and reducing the compressive strength of the finishing.

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 paperboard, and the pressure of the side is lowered, and the compressive strength is also reduced.

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 paper will be separated from the corrugated paper after being pressed, and the compressive strength will drop linearly.
