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.

這樣就要把縮小的那部分尺寸加進(jìn)去，這個(gè)加進(jìn)去的尺寸與使用的瓦楞紙板的厚度密切相關(guān)。瓦楞紙箱在實(shí)際生產(chǎn)中還要根據(jù)具體使用的設(shè)備選擇適當(dāng)?shù)男拚禂?shù)和附加尺寸。修正系數(shù)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.

制作瓦楞紙箱一般都是根據(jù)內(nèi)徑尺寸來設(shè)計(jì)的。因?yàn)閮?nèi)徑尺寸比較容易確定，它以實(shí)物測量或者以組合套裝、合理的排列方式的外徑尺寸來實(shí)現(xiàn)并確定。但在實(shí)際操作中，無論是運(yùn)費(fèi)的計(jì)算，還是箱面標(biāo)志中的體積，都要以外徑尺寸為準(zhǔn)。因此在瓦楞紙箱設(shè)計(jì)中，不僅要根據(jù)內(nèi)徑尺寸來確定制造尺寸，還要根據(jù)制造尺寸計(jì)算出外徑尺寸。

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.

當(dāng)然，也可根據(jù)托盤或集裝箱的內(nèi)徑尺寸來確定紙箱的外徑尺寸，使紙箱的長、寬、高與運(yùn)輸工具相適應(yīng)，實(shí)現(xiàn)機(jī)械化運(yùn)輸，提高運(yùn)輸效率。由于瓦楞紙箱的堆碼方式不同，故應(yīng)使堆碼物體的垂直投影面積與托盤尺寸相適合。若能讓紙箱從內(nèi)向外逐級(jí)計(jì)算的箱體尺寸與由外向內(nèi)逐級(jí)計(jì)算的箱體尺寸基本吻合，則可得到化的瓦楞紙箱尺寸。當(dāng)然，設(shè)計(jì)方案還是應(yīng)由外向內(nèi)逐級(jí)進(jìn)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.

實(shí)際生產(chǎn)中，客戶提供給我們的往往只有內(nèi)裝產(chǎn)品的尺寸或樣式，這就需要我們計(jì)算出紙箱的外徑尺寸和制造尺寸。特別是采用集裝箱運(yùn)輸?shù)漠a(chǎn)品，對(duì)紙箱外徑的計(jì)算尤為重要。在對(duì)瓦楞紙箱進(jìn)行測量時(shí)，雖然都可以直接用工具測量出其具體的尺寸，然而在測量的過程中，由于壓痕線的影響，會(huì)導(dǎo)致測量的結(jié)果不夠精確。

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.

特別是對(duì)使用過的廢舊紙箱尺寸的測量，應(yīng)嚴(yán)格測算，以保證尺寸設(shè)計(jì)的準(zhǔn)確性，保證后期托盤或集裝箱裝柜順利進(jìn)行，并能很好的保護(hù)商品。一個(gè)好的紙箱設(shè)計(jì)方案可以在運(yùn)輸上節(jié)約大量的成本。

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.
