core tip: at present, the flow of products and materials is an important part of economic activities, which starts from the production plant and ends at the consumer, including the transportation of goods and packaging Transit, loading and unloading, warehousing, display, sales and other links. Nowadays, new packaging technologies emerge in endlessly, such as cushioning and shockproof packaging, collective packaging, theft proof packaging, children's safety packaging, anti-counterfeiting packaging, fresh-keeping packaging, vacuum packaging, etc. As a carton cushioning structure that embodies the function of protecting products, its characteristics in cartons recommend that the material experimental load is about 70% - 90% of the range of the experimental machine, and the design is ever-changing.

[China Packaging News] at present, the circulation of products and materials is an important part of economic activities. It starts from the production factory and ends at the consumer, including the transportation, transit, loading and unloading, storage, display, sales and other links of commodities and packaging. Nowadays, new packaging technologies emerge in endlessly, such as cushioning and shockproof packaging, collective packaging, theft proof packaging, children's safety packaging, anti-counterfeiting packaging, fresh-keeping packaging, vacuum packaging, etc. As a carton buffer structure that embodies the function of protecting products, it is ever-changing in the characteristic design of cartons. This paper tries to analyze the structure of paperboard folding cushioning packaging

comprehensive cushioning packaging structure

comprehensive cushioning packaging method mainly refers to filling the buffer material between the product and the carton so that all sides are fixed by the cardboard, and adopting a comprehensive protection method for the product. Its advantage is that it is suitable for product packaging with complex shape and small batch, and the buffer material has a large contact area with the product, the static stress is small, and it can absorb large impact energy, and the buffer thickness is small, which can reduce the size of the package and reduce the logistics cost; However, this kind of buffer structure uses a lot of materials, and some parts that do not need buffer also use materials of the same thickness, which is more wasteful and costly to pack. Its structure can be divided into single wall buffer structure and combined buffer structure

(I) single wall buffer structure

single wall buffer structure is a buffer structure folded from a single piece of paperboard through cutting, indentation, folding and other processes. It forms a baffle around the product, and there is part of the support outside the baffle, which plays the role of separating the product from the outer packaging box. This buffer structure not only saves materials, but also can achieve the strength required by the product, and can be used to pack some light quality products, As shown in Figure 1 below

(II) combined buffer structure

the combined buffer structure is composed of two or more pieces of cardboard by folding, forming double-layer or multi-layer cardboard around the product. Compared with the single wall buffer structure, this buffer structure uses more materials, but has high strength and can withstand greater impact. Therefore, it can be used for packaging with higher quality. The Indian designer anirud produces large quantities of products leading this design, as shown in Figure 2 below. This is a double wall buffer structure, which is placed in the outer packing box as a whole
