In the process of protecting and displaying cakes, the anti-deformation structure and technology of Cake Box play a key role.
In terms of material selection, this is the cornerstone of building a stable Cake Box. High-quality thick cardboard or corrugated paper with a certain strength is an ideal choice. The stiffness of the cardboard can provide a basic support frame for the box body, so that it can maintain its shape during regular handling and placement. The unique sandwich structure of corrugated paper, such as the common E-type and B-type corrugated paper, can effectively disperse external forces. For example, the fine corrugation of E-type corrugated paper can provide better buffering and support in a smaller space, which is suitable for small and exquisite Cake Boxes; B-type corrugated paper is more suitable for packaging larger and heavier cakes, and its larger corrugated spacing can withstand greater pressure.
The structural design link is crucial. The corners of the box body can be rounded or additional reinforcement sheets can be added. Rounded corners can reduce the concentrated impact of external forces, and the reinforcement sheets are like putting "armor" on the box body. The box wall adopts a double-layer or multi-layer structure to form a "sandwich"-like structure to enhance the overall compression resistance. For example, honeycomb cardboard can be added in the middle of the double-layer box wall. This structure, with its unique hexagonal honeycomb arrangement, evenly distributes the pressure in all directions, greatly improving the anti-deformation ability of the box wall. At the same time, the fit between the box cover and the box body is also very particular. For example, the nested design is adopted, and the box cover is tightly embedded in a part of the box body, which can not only prevent the box cover from sliding off easily, but also restrain the box body in the vertical direction, reducing the deformation caused by the pressure from above.
Internal support elements are a powerful supplement to anti-deformation. Placing a suitable partition or tray inside the Cake Box is of great significance to maintaining the shape of the Cake Box. For a round Cake Box, the round partition can accurately match the bottom of the cake, evenly distribute the weight of the cake, and avoid local compression and deformation of the bottom of the box. For a multi-layer Cake Box, the support column or tray between the layers must have sufficient strength and stability to bear the weight of the upper cake and the box body, and smoothly transfer it to the lower structure to prevent the box body from collapsing and deforming due to the pressure between the layers.
Production process and quality control are the last line of defense against deformation. Precise die-cutting technology ensures that the dimensions of each component are accurate and that they fit together perfectly when assembled. For example, precise fold line die-cutting allows the cardboard to be folded naturally and smoothly, avoiding structural distortion caused by fold line deviation. After forming, strict quality inspection is essential. Pressure testing equipment is used to simulate various pressure conditions that the Cake Box may encounter during transportation and storage, and to check for signs of deformation. Only strictly tested Cake Boxes can ensure effective deformation prevention in actual use and provide a reliable "home" for cakes.
