In the dry weather in winter, many carton factories are troubled by the problem of carton production line explosion. The line explosion not only seriously affects the carton quality and the loss rate rises sharply, but also delays the delivery date, resulting in serious economic losses to the carton factory. So what is the reason for the carton packaging burst? How to solve it?

纸箱包装纸是一种亲水性物质，吸水会变软变韧，失水则变硬变脆。当纸板的水分含量偏低时，水分对瓦楞纸箱爆线的影响主要表现在两个方面：

Carton wrapping paper is a hydrophilic material. It will become soft and tough when absorbing water, and hard and brittle when losing water. When the moisture content of the paperboard is low, the influence of moisture on the bursting line of the corrugated box is mainly reflected in two aspects:

1.面里纸耐折性下降，纸板的挺度增加，包装纸箱爆线的可能性增加

1. The folding resistance of the surface paper decreases, the stiffness of the paperboard increases, and the possibility of line burst of the packaging carton increases

2.纸板芯平压强度增加，面里纸韧性下降，在进行压线时容易损坏面里纸，造成纸箱爆线。

2. The flat pressing strength of the paperboard core increases and the toughness of the paper in the surface decreases. It is easy to damage the paper in the surface when pressing the line, resulting in the line explosion of the carton.

纸箱包装爆线改善方法：

Improvement method for carton packaging burst:

1.纸箱包装纸板生产出来后应该堆放足够的时间，等各层纸的水分达到平衡后再上机印刷。纸板面、里纸水分偏低即进行印刷压线，压线部位会产生微裂，此后即使面、里纸水分增加，爆线问题也不可能避免。

1. After the production of carton packaging paperboard, it should be stacked for enough time, and then printed on the machine after the moisture of each layer of paper reaches balance. When the moisture of the paper board surface and inner paper is low, the printing line pressing will be carried out, and the line pressing part will produce micro cracks. After that, even if the moisture of the surface and inner paper increases, the line burst problem can not be avoided.

2.纸箱包装如果交货时间太短，无法有充分的时间让纸板水分平衡，给纸板表面湿水是直接也是很好的办法。湿水时避免波及印刷部位，否则会对印刷造成不良影响。假如条件许可，可利用废旧实地版制作一块湿水版，先用一座印刷站对压线部位湿水，然后再进行印刷。这样即可以对压线位进行快速湿水，又不影响印刷质量。

2. If the delivery time of carton packaging is too short to allow sufficient time for the water balance of the paperboard, it is a direct and good way to wet the surface of the paperboard. Avoid affecting the printing part when wet, otherwise it will have an adverse impact on the printing. If conditions permit, you can use the waste field version to make a wet version. First wet the line pressing part with a printing station, and then print. In this way, the line pressing position can be wet quickly without affecting the printing quality.
