Packaging structure design is based on the actual conditions of packaging and production, according to the scientific principle of packaging structure and internal accessories design. The design must ensure that the structure has sufficient strength, hardness and the ability to resist other environments. From the purpose of packaging, we must consider the following two aspects: one is to protect the primary function of products; the other is to meet the important characteristics of modern packaging, such as transportation, processing characteristics.

合格的纸箱产品，从正确的结构设计开始。设计人员不仅要真正的理解客户的意图，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, starting from the correct structural design. Designers should not only truly 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 the subsequent processing can be ensured smoothly. Before the design starts, the designer should know the nature, shape, size and weight of the contents, the arrangement, transportation and stacking methods of the contents, the storage environment, transportation route and time of the contents, as well as the carton type 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，在目前的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 current carton size design.

目前，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，才能够真正合理地确定纸箱的尺寸大小。

At present, our country only has made the clear stipulation to the box type of the carton, but has no specific request to the size of the carton, which is mainly decided 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; the other is to have sufficient strength. In fact, there are many other factors that restrict the size and shape of cartons besides the contents of packages, such as ergonomic factors, the size of pallets, the size of freight cars, the size of container space, and the size of distribution rack. These factors are not only independent of each other, but also influence each other; both packaging function and convenience should be considered. Therefore, only by systematically and comprehensively grasping all the restrictive factors can the size of the carton be determined reasonably.
