瓦楞纸板是由面纸、里纸、芯纸和加工成波形瓦楞的瓦楞纸通过粘合而成。根据商品包装的需求，瓦楞纸板可以加工成单面瓦楞纸板、三层瓦楞纸板、五层、七层、十一层等瓦楞纸板。
Corrugated board is made of face paper, lining paper, core paper and corrugated paper processed into corrugated by bonding. According to the demand of commodity packaging, corrugated board can be processed into single-sided corrugated board, three-layer corrugated board, five layer, seven layer, eleven layer corrugated board.
不同波纹形状的瓦楞，粘结成的瓦楞纸板的功能也有所不同。即使使用同样质量的面纸和里纸，由于楞形的差异，构成的瓦楞纸板的性能也有一定区别。目前上通用的瓦楞楞形分为四种，它们分别是A型楞、C型楞、B型楞和E型楞。它们的技术指标和要求见表一。A型楞制成的瓦楞纸板具有较好的缓冲性，富有一定的弹性，C型楞较A型楞次之。但挺度和抗冲击性优于A型楞；B型楞排列密度大，制成的瓦楞纸板表面平整，承压力高，适于印刷；E型楞由于薄而密，更呈现了它的刚强度。
Different corrugations have different functions. Even if the same quality of face paper and inside paper are used, there are some differences in the performance of the corrugated board due to the difference of the corrugated shape. At present, there are four kinds of corrugating shapes in the world, they are A-type, C-type, B-type and E-type. Their technical indicators and requirements are shown in Table 1. The corrugated board made of A-type corrugated board has better cushioning and elasticity, followed by C-type corrugated board. But its stiffness and impact resistance are better than that of A-type corrugated board; B-type corrugated board has a large arrangement density, the surface of the corrugated board made is flat, the bearing pressure is high, and it is suitable for printing; E-type corrugated board is thin and dense, which shows its rigidity and strength.
集装箱和非集装箱的区别主要在于外径，并且与瓦楞类型密切相关。下面将通过下表详细罗列出纸箱内径规格、制造规格、外径规格之间的关系：
The difference between container and non container mainly lies in the outer diameter, which is closely related to the type of corrugation. The following table will detail the relationship between the inner diameter specification, manufacturing specification and outer diameter specification of the carton:

瓦楞纸箱制造尺寸的量法
Measuring method for manufacturing dimensions of corrugated boxes
纸箱的制造尺寸为制箱时的下料尺寸。制造尺寸以展开的箱坯上的压线为度量的基准。分切机上的压痕辊在压线位置上压出的是一条沟， 压线是这条沟槽的线。两条压线的距离就是制造尺寸。将制造尺寸转换为内、外径尺寸可以通过表 2 速成，但它们也分别有自己的测量方法。
The manufacturing dimension of cartons is the cutting dimension during cartoning. The manufacturing dimension is measured by the pressing line on the expanded box blank. The indentation roll on the slitting machine presses out a groove at the pressing line position, and the pressing line is the center line of the groove. The distance between the two pressing lines is the manufacturing dimension. The conversion of manufacturing dimensions to internal and external dimensions can be done quickly in Table 2, but they also have their own measurement methods.
瓦楞纸箱在制造过程中有单拼和双拼之分
There are two kinds of corrugated boxes: single and double in the manufacturing process
单拼即一页成型箱 , 一般用于周长较小的纸箱；双拼也称为二页箱，有的纸箱周长太大，不得不用两片箱坯拼凑一个纸箱，但有时纸箱厂为了利用生产过程中 裁切下来的余料，也会用两片拼凑一个尺寸不算太大的纸箱，甚有时会用四片。二页箱与一页箱相比，多了一个接头，因此两者的面积 计算有一些细微的差别。
Single splicing refers to one page forming box, which is generally used for cartons with smaller perimeter; double splicing is also called two page box. Some cartons have too long perimeter, so they have to use two pieces of box blank to assemble a carton, but sometimes in order to make use of the surplus materials cut in the production process, the carton factory will also use two pieces to assemble a carton that is not too large, or even four pieces. Compared with one page box, two page box has one more joint, so there are some subtle differences in the area calculation between the two.
