Methods and principles in corrugated box design

The packaging structure design is based on the actual conditions of packaging and production, and based on scientific principles, the external structure and internal accessories of the packaging are designed. The design must ensure that the structure has sufficient strength, hardness and the ability to resist other environments. From the purpose of packaging, the following two aspects must be considered, one is to protect the primary function of the product, and the other is to meet the important characteristics of modern packaging, such as transportation, processing characteristics, etc.

Qualified carton products start from the correct structural design. Designers must 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 a qualified product, and the subsequent processing can be ensured smoothly. Before starting the design, designers should understand the nature, shape, size, weight of the contents, the arrangement, transportation, stacking methods of the contents, the storage environment, transportation route and time of the contents, as well as the carton type and production materials, etc. information.

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

Our country only makes clear regulations on the box shape of the carton, but there is no specific requirement for the size of the carton, which is mainly determined by the designer. The designer mainly considers two factors when determining the size of the carton: one is to be able to accommodate the contents; the other is to have sufficient strength. In fact, in addition to the contents of the package, there are many other factors that restrict the size and shape of the carton, such as ergonomic factors, the size of the pallet, the size of the truck compartment, the size of the container space, the size of the shelves size etc. These factors are not only independent of each other, but also restrict each other; it is necessary to consider both the packaging function and the convenience. Therefore, only by systematically and comprehensively grasping all the constraints in the design can the size of the carton be truly and reasonably determined.
