The reason for this may be that the guide jaw assembly is too tight, resulting in a loose or weakly adhesive tissue. The carton's compressive strength and paperboard side compressive strength are reduced.
Simply put, it is because the amount of glue on the gluing is not sufficient, resulting in loose bonding of the paper core paper. Other possible causes are: the distance between the top roller and the metering roller or the paste doctor blade is too small; the gap between the paste roller and the lower corrugating roller is too large; or the over-tight metering roller paste blade pressure makes the metering roller inward Bending, thereby reducing the metering gap in the middle.
