Packaging structure design is based on the actual conditions of packaging and production, according to the scientific principle of the design of the external structure and internal accessories of packaging. The design should ensure that the structure has enough strength, hardness and resistance to other environments. From the perspective of the purpose of packaging, the following two aspects should be considered: one is to protect the primary function of the product, the other is to meet the important characteristics of modern packaging, such as transportation and processing characteristics.

合格的紙箱產(chǎn)品，從正確的結(jié)構(gòu)設(shè)計開始。設(shè)計人員不僅要理解客戶的意圖，還要熟悉后序加工工藝。只有這樣，才能把客戶的意圖轉(zhuǎn)化為合格的產(chǎn)品，并能保證后序加工順利進行。設(shè)計人員在設(shè)計開始前要了解內(nèi)裝物的性質(zhì)、形狀、尺寸、重量，內(nèi)裝物的排列方式、運輸方式、堆碼方式，內(nèi)裝物的倉儲環(huán)境、運輸路線和時間以及紙箱箱型和制作材料等信息。

Qualified carton products start from the correct structural design. Designers should not only understand the customer's intention, but also be familiar with the subsequent processing technology. Only in this way, can the customer's intention be transformed into qualified products, and can ensure the smooth progress of subsequent processing. Before design, designers should understand the nature, shape, size and weight of the contents, the arrangement, transportation mode and stacking mode of the contents, the storage environment, transportation route and time of the contents, as well as the type of cartons and manufacturing materials.

國內(nèi)的紙箱設(shè)計，存在技術(shù)和指導(dǎo)思想方面的一些問題，缺乏系統(tǒng)的分析，從而使得所設(shè)計出來的包裝不能夠滿足人機工程學(xué)以及技術(shù)經(jīng)濟合理性等方面的要求。這一點，在紙箱尺寸設(shè)計中反映得十分明顯。

Domestic carton design, there are some technical and guiding ideology problems, lack of systematic analysis, so that the designed packaging can not meet the requirements of ergonomics and technical and economic rationality. This is very obvious in the design of carton size.

我國只是對紙箱的箱型作了明確的規(guī)定，而對紙箱的尺寸大小卻無具體要求，主要由設(shè)計者來定。而設(shè)計者在確定紙箱尺寸時又主要是考慮兩方面的因素：一是能夠包容得下內(nèi)容物；二是具有足夠的強度。其實，制約紙箱大小和形狀的因素除去包裝內(nèi)容物外，還有許多其它的因素，如人機工程學(xué)方面的因素、托盤的尺寸、貨車車廂的尺寸大小、集裝箱空間的尺寸大小、配貨架的尺寸大小等。這些因素間既相互獨立，又相互制約影響；既要考慮包裝功能，也要考慮方便性。所以設(shè)只有系統(tǒng)地、綜合地把握住所有的制約因素，才能夠合理地確定紙箱的尺寸大小。

In China, only the type of the carton is specified, but there is no specific requirement for the size of the carton, which is mainly determined by the designer. The designer in determining the size of the carton is mainly to consider two factors: one is to be able to contain the contents; Second, it has enough strength. In fact, in addition to the package contents, there are many other factors that restrict the size and shape of cartons, such as ergonomics, pallet size, truck compartment size, container space size, distribution rack size, etc. These factors are not only independent but also restrict each other; We should consider not only the packaging function but also the convenience. Therefore, only when we grasp all the restrictive factors systematically and comprehensively can we determine the size of the carton reasonably.

綜上所述，紙箱的尺寸設(shè)計是瓦楞紙箱結(jié)構(gòu)設(shè)計中很重要的一項工作。一個合格的紙箱產(chǎn)品要具有保護性和良好的造型。特別是集銷售包裝和運輸包裝功能于一身的紙箱，合理的尺寸將是紙箱設(shè)計的關(guān)鍵。因為尺寸的變化將直接影響到紙箱的各種性能的變化。總之，在瓦楞紙箱的結(jié)構(gòu)設(shè)計中，要根據(jù)使用的制造設(shè)備、不同的生產(chǎn)工藝、不同楞型構(gòu)成的瓦楞紙以及內(nèi)裝商品的種類和性質(zhì)來確定。只有掌握了設(shè)計瓦楞紙箱的結(jié)構(gòu)、尺寸相關(guān)的內(nèi)容后，才能制造出保護商品、美化商品的瓦楞紙箱。

To sum up, the size design of the corrugated box is a very important work in the structural design of the corrugated box. A qualified carton product should have protection and good shape. In particular, the reasonable size will be the key to the design of the carton, which integrates the functions of sales packaging and transportation packaging. Because the change of size will directly affect the change of various properties of the carton. In a word, in the structural design of corrugated box, it should be determined according to the manufacturing equipment used, different production processes, corrugated paper formed by different types of corrugated paper and the types and properties of goods inside. Only after mastering the structure and size of the corrugated box, can we make the corrugated box to protect and beautify the goods.
