包装结构设计是从包装和生产实际条件出发，依据科学原理对包装的外形构造及内部附件进行的设计。设应保证结构有足够的强度、硬度及抵抗其他环境的能力。从包装的目的来看，应考虑以下两个方面，一是保护产品的首要功能，二是满足现代包装的重要特征，如运输、加工特性等。
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.
合格的纸箱产品，从正确的结构设计开始。设计人员不仅要理解客户的意图，还要熟悉后序加工工艺。只有这样，才能把客户的意图转化为合格的产品，并能保证后序加工顺利进行。设计人员在设计开始前要了解内装物的性质、形状、尺寸、重量，内装物的排列方式、运输方式、堆码方式，内装物的仓储环境、运输路线和时间以及纸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.
国内的纸箱设计，存在技术和指导思想方面的一些问题，缺乏系统的分析，从而使得所设计出来的包装不能够满足人机工程学以及技术经济合理性等方面的要求。这一点，在纸箱尺寸设计中反映得十分明显。
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.
我国只是对纸箱的箱型作了明确的规定，而对纸箱的尺寸大小却无具体要求，主要由设计者来定。而设计者在确定纸箱尺寸时又主要是考虑两方面的因素：一是能够包容得下内容物；二是具有足够的强度。其实，制约纸箱大小和形状的因素除去包装内容物外，还有许多其它的因素，如人机工程学方面的因素、托盘的尺寸、货车车厢的尺寸大小、集装箱空间的尺寸大小、配货架的尺寸大小等。这些因素间既相互独立，又相互制约影响；既要考虑包装功能，也要考虑方便性。所以设只有系统地、综合地把握住所有的制约因素，才能够合理地确定纸箱的尺寸大小。
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.
综上所述，纸箱的尺寸设计是瓦楞纸箱结构设计中很重要的一项工作。一个合格的纸箱产品要具有保护性和良好的造型。特别是集销售包装和运输包装功能于一身的纸箱，合理的尺寸将是纸箱设计的关键。因为尺寸的变化将直接影响到纸箱的各种性能的变化。总之，在瓦楞纸箱的结构设计中，要根据使用的制造设备、不同的生产工艺、不同楞型构成的瓦楞纸以及内装商品的种类和性质来确定。只有掌握了设计瓦楞纸箱的结构、尺寸相关的内容后，才能制造出保护商品、美化商品的瓦楞纸箱。
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.
