瓦楞纸板经过模切、压痕、钉箱或粘箱制成瓦楞纸箱。
瓦楞纸箱是一种应用更广的包装制品，用量一直是各种包装制品之首。那么瓦楞纸箱对于强度有哪些方面的要求？今天国泰民沣小编就带大家来了解一下：
Corrugated paperboard through die-cutting, indentation, nailing or gluing into corrugated boxes. Corrugated box is one of the most widely used packaging products, and its consumption is always the first of all kinds of packaging products. So what are the requirements of corrugated box for strength? Today, I'd like to take you to know:
1、瓦楞纸板强度要求
1. Strength requirements of corrugated board
1．1：边压强度：顺着瓦楞方向，单位长度瓦楞纸板压馈前所能承受的受力。单位： N/m.
1.1: edge pressure strength: the maximum stress that the unit length corrugated board can bear before feeding along the corrugated direction. Unit: n / m
边压强度=表面原纸综合环压强度+综合瓦楞纸环压强度*收缩率
Edge crush strength = surface base paper comprehensive ring crush strength + comprehensive corrugated paper ring crush strength * shrinkage
一般边压计算依原纸环压强度计算（可靠），实际测试值会适当大于理论计算值。
Generally, the calculation of edge pressure is based on the minimum ring crush strength of base paper (safe and reliable), and the actual test value will be appropriately greater than the theoretical calculation value.
1．2：耐破强度：单位面积瓦楞纸板破裂前所能承受均匀增加的外力。单位： Kg/cm2。
1.2: bursting strength: the maximum external force that the corrugated paperboard can bear before it breaks. Unit: kg / cm2.
纸板破裂强度=面纸破裂强度+中格纸破裂强度+底纸破裂强度
Breaking strength of paperboard = breaking strength of face paper + breaking strength of medium grid paper + breaking strength of base paper
*因制造过程会有一定强度损失，实际测试的破裂强度会小于计算值1 Kg/cm2左右。
*Due to certain strength loss in the manufacturing process, the actual test fracture strength will be less than the calculated value of 1 kg / cm2.
1．3：戳穿强度：新的标准GB6544-1999已经取消了对纸板戳穿强度的要求。（原标准GB6544-1986）
1.3: puncture strength: the new national standard gb6544-1999 has cancelled the requirements for the puncture strength of paperboard. (original standard gb6544-1986)
2、瓦楞纸箱强度要求：
2. Strength requirements of corrugated box:
2．1：边压、耐破、戳穿同纸板。纸箱边压强度会比纸板边压强度要低（因制造过程的瓦楞损失）。
2.1: edge pressing, bursting resistance and puncturing are the same as those of paperboard. The edge crush strength of the carton is lower than that of the cardboard (due to the corrugated loss in the manufacturing process).
2．2：纸箱抗压强度：（普通箱型，对应箱型代号：0201）
2.2: compressive strength of carton: (ordinary box type, corresponding to international box type code: 0201)
抗压强度=边压强度（N/cm）*凯里卡特常数F
Compressive strength = edge compressive strength (n / cm) * Kerry Carter constant f
F值取决于纸箱的周边长，2*（长+宽）cm.以及瓦楞楞型。两项目确定后，F值可以查表。实际上的抗压强度测试值与纸箱长、宽、高的比例有关系。同样周边长、同样材质楞型的纸箱：高度越高、抗压越小；长*宽的底面积越大，抗压越大。
The F value depends on the perimeter length of the carton, 2 * (L + W) cm. And the corrugated type. After the two items are determined, the F value can be checked in the table. In fact, the compressive strength test value is related to the ratio of carton length, width and height. For the same material, the longer the corrugated bottom is, the smaller the compression area is.
3、机包箱抗压强度=对应普通箱型的抗压强度*0.6*1.62*摇盖宽/纸箱宽 。
3. The compressive strength of the machine case = the compressive strength of the corresponding ordinary box type * 0.6 * 1.62 * the width of the shaking cover / the width of the carton.
4、纸箱、纸板的粘合强度（瓦楞成型的剥离强度而不是接舌处粘箱的粘合强度）。分离单位长度纸板面纸与瓦楞纸所需的力。
4. The adhesive strength of carton and paperboard (peeling strength of corrugated forming rather than adhesive strength of glued box at tongue joint). The force required to separate the surface paper and corrugated paper per unit length.
单位：N/m楞。行业标准统一规定为大于588 N/m楞.
Unit: n / m. The industry standard is more than 588 n / m
5、堆码强度与抗压强度。
5. Stacking strength and compressive strength.
纸箱所需抗压强度=[纸箱毛重*（堆码层数-1）]*系数K。前部分为纸箱的静态堆码强度。K值取决于印刷版面的多少、开孔程度、内包装物性质、贵重程度、仓储运输时间、条件等。K值一般取2—5。
The required compressive strength of the carton = [carton gross weight * (stacking layers - 1)] * safety factor K. The front part is the static stacking strength of the carton. The value of K depends on the number of printed pages, the degree of opening, the nature of the inner packaging, the degree of value, storage and transportation time, conditions, etc. The value of K is generally 2-5.
