makecorrugated cardboard boxIt is usually designed based on the inner diameter size. Because the inner diameter size is relatively easy to determine, it is achieved and determined through physical measurement or by combining the outer diameter size in a set and reasonable arrangement. But in practical operation, whether it is the calculation of freight or the volume marked on the box surface, the outer diameter size should be used as the standard. Therefore, in the design of corrugated cardboard boxes, it is not only necessary to determine the manufacturing size based on the inner diameter size, but also to calculate the outer diameter size based on the manufacturing size.

Packaging structure design is the design of the external structure and internal accessories of packaging based on scientific principles, starting from the actual conditions of packaging and production. When designing, it is necessary to ensure that the structure has sufficient strength, hardness, and the ability to resist other environments. From the purpose of packaging, two aspects must be considered: first, protecting the primary function of the product, and second, meeting the important features of modern packaging, such as transportation and processing characteristics.

Qualified cardboard products start with the correct structural design. Designers not only need to truly understand the client's intentions, but also be familiar with the post-processing technology. Only in this way can customer intentions be transformed into qualified products and ensure smooth subsequent processing. Designers need to understand the nature, shape, size, weight, arrangement, transportation, and stacking methods of the contents, the storage environment, transportation route, and time of the contents, as well as the type of cardboard boxes and production materials before starting the design.
