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?

紙箱包裝紙是一種親水性物質，吸水會變軟變韌，失水則變硬變脆。當紙板的水分含量偏低時，水分對瓦楞紙箱爆線的影響主要表現在兩個方面：

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.面里紙耐折性下降，紙板的挺度增加，包裝紙箱爆線的可能性增加

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.紙板芯平壓強度增加，面里紙韌性下降，在進行壓線時容易損壞面里紙，造成紙箱爆線。

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.

紙箱包裝爆線改善方法：

Improvement method for carton packaging burst:

1.紙箱包裝紙板生產出來后應該堆放足夠的時間，等各層紙的水分達到平衡后再上機印刷。紙板面、里紙水分偏低即進行印刷壓線，壓線部位會產生微裂，此后即使面、里紙水分增加，爆線問題也不可能避免。

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.紙箱包裝如果交貨時間太短，無法有充分的時間讓紙板水分平衡，給紙板表面濕水是直接也是很好的辦法。濕水時避免波及印刷部位，否則會對印刷造成不良影響。假如條件許可，可利用廢舊實地版制作一塊濕水版，先用一座印刷站對壓線部位濕水，然后再進行印刷。這樣即可以對壓線位進行快速濕水，又不影響印刷質量。

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.
