一般瓦楞纸板需通过模压工艺使之能得到良好的弯折。模压使瓦楞纸板的结构破坏，会导致里纸收缩、面纸延伸，这种弯折变化使瓦楞纸板的延伸尺寸成了瓦楞纸箱设计的基本尺寸。所以，瓦楞纸箱的内径尺寸要比瓦楞纸箱展开时的线与压线间的距离要略短一些。
Generally, corrugated paperboard needs to be molded to make it bend well. The structure of corrugated board will be destroyed by die pressing, which will lead to the shrinkage of inner paper and the extension of top paper. This kind of bending change makes the extension size of corrugated board become the basic size of corrugated box design. Therefore, the inner diameter of the corrugated box is slightly shorter than the distance between the line and the pressure line when the corrugated box is unfolded.
这样就要把缩小的那部分尺寸加进去，这个加进去的尺寸与使用的瓦楞纸板的厚度密切相关。瓦楞纸箱在实际生产中还要根据具体使用的设备选择适当的修正系数和附加尺寸。修正系数值查表可得到。
In this way, the reduced part of the size is added in, which is closely related to the thickness of the corrugated board used. In the actual production of corrugated box, the appropriate correction coefficient and additional size should be selected according to the specific equipment used. The correction coefficient can be obtained by looking up the table.
制作瓦楞纸箱一般都是根据内径尺寸来设计的。因为内径尺寸比较容易确定，它以实物测量或者以组合套装、合理的排列方式的外径尺寸来实现并确定。但在实际操作中，无论是运费的计算，还是箱面标志中的体积，都要以外径尺寸为准。因此在瓦楞纸箱设计中，不仅要根据内径尺寸来确定制造尺寸，还要根据制造尺寸计算出外径尺寸。
Making corrugated box is generally based on the inner diameter of the design. Because the inner diameter size is easy to determine, it can be realized and determined by physical measurement or external diameter size of combination set and reasonable arrangement. However, in practice, both the calculation of freight and the volume in the mark on the box surface should be based on the outer diameter. Therefore, in the design of corrugated box, we should not only determine the manufacturing size according to the inner diameter, but also calculate the outer diameter according to the manufacturing size.
当然，也可根据托盘或集装箱的内径尺寸来确定纸箱的外径尺寸，使纸箱的长、宽、高与运输工具相适应，实现机械化运输，提高运输效率。由于瓦楞纸箱的堆码方式不同，故应使堆码物体的垂直投影面积与托盘尺寸相适合。若能让纸箱从内向外逐级计算的箱体尺寸与由外向内逐级计算的箱体尺寸基本吻合，则可得到化的瓦楞纸箱尺寸。当然，设计方案还是应由外向内逐级进行。
Of course, the outer diameter of the carton can also be determined according to the inner diameter of the pallet or container, so that the length, width and height of the carton can adapt to the means of transportation, realize the mechanized transportation and improve the transportation efficiency. Due to the different stacking methods of corrugated boxes, the vertical projection area of stacked objects should be suitable for the pallet size. If the box size calculated step by step from the inside to the outside is basically consistent with the box size calculated step by step from the outside to the inside, the optimal size of the corrugated box can be obtained. Of course, the best design scheme should be carried out step by step from outside to inside.
实际生产中，客户提供给我们的往往只有内装产品的尺寸或样式，这就需要我们计算出纸箱的外径尺寸和制造尺寸。特别是采用集装箱运输的产品，对纸箱外径的计算尤为重要。在对瓦楞纸箱进行测量时，虽然都可以直接用工具测量出其具体的尺寸，然而在测量的过程中，由于压痕线的影响，会导致测量的结果不够精确。
In actual production, customers often only provide us with the size or style of the inner product, which requires us to calculate the outer diameter and manufacturing size of the carton. Especially for the products transported in containers, the calculation of carton outer diameter is particularly important. In the measurement of corrugated box, although the specific size can be directly measured with tools, but in the process of measurement, due to the influence of indentation line, the measurement results are not accurate enough.
特别是对使用过的废旧纸箱尺寸的测量，应严格测算，以保证尺寸设计的准确性，保证后期托盘或集装箱装柜顺利进行，并能很好的保护商品。一个好的纸箱设计方案可以在运输上节约大量的成本。
In particular, the size measurement of used waste cartons should be strictly measured to ensure the accuracy of the size design, ensure the smooth loading of pallets or containers in the later stage, and protect the goods well. A good carton design can save a lot of cost in transportation.
