If the carton has insufficient pressure, it is not necessarily a problem with cardboard!
Many secondary factories will receive customer complaints from the third-level factory, saying that the physical indicators of the Carton are not up to standard. When there is insufficient pressure on the empty box in the carton, many people consider the material of the paper and the problem of the tile process. In fact, the printing press will also cause the problem of insufficient pressure resistance of the empty box, for example: 1. When the paper is separated, the cardboard passes through the machine and will be pressed to the corrugated board, which will affect the thickness of the corrugated box and reduce the pressure resistance of the empty box of the corrugated box. 2. When the paper feed wheel of the printing machine is improperly adjusted, the pressure difference of the machine is crushed, which will also affect the thickness of the corrugated box and reduce the pressure resistance of the empty box of the corrugated box. 3. When the printing pressure of the printing press is relatively large, the corrugated cardboard will be destroyed, so the empty box of the corrugated box will also be insufficiently pressed. Therefore, it is necessary to control the pressure gaps of the printing press during the printing machine production process. 4. When the slotting position is not accurate, it will also cause insufficient pressure resistance of the empty box of the carton. If the carton slot appears -4mm, it will affect the pressure resistance, because the carton is mainly pressed by the four corners of the carton, and the position of the corner is not accurate, which will reduce the compression resistance. Therefore, to ensure that the empty box is resistant to pressure, the slotting position is also quite important. 4. The carton pressure line is not correct, and the crushing wheel crushing large will also cause insufficient pressure resistance. When the cardboard is easy to burst, the press personnel will increase the pressure of the crushing wheel. Once the carton is formed, the four right angles become rounded corners, which will also cause insufficient pressure resistance. Therefore, when the pressure resistance of the carton is insufficient, it is necessary to consider and observe from various aspects to find the real reason for improvement.
