The reason why corrugated boxes can be sturdy and durable is mainly due to the following aspects:

The choice of corrugated cardboard: The thickness and shape of the corrugated cardboard directly affect the carton's bearing capacity and compression resistance. Generally speaking, the thicker the corrugated carton, the stronger the carrying capacity, but the cost will also increase accordingly.

Structural design: When designing the carton structure, it is necessary to consider the supporting and cushioning functions of the box. A reasonable design can disperse the strength of the box and reduce the pressure, thereby increasing the load-bearing capacity and impact resistance of the box. For example, by enhancing the pressure point, the pressure on the box is more uniform, thereby improving the load-bearing capacity.

Materials used: In addition to corrugated cardboard, other materials can also be added to the production of cartons, such as cushioning materials, glue, sealing tape, etc., to enhance the carton's load-bearing capacity and compression resistance.

Processing technology: The processing technology of the carton also affects its durability, such as the cutting, folding, and bonding of the cardboard, which requires fine processing to ensure the integrity and stability of the carton.

In summary, to achieve strong and durable corrugated boxes, we need to start from multiple aspects, from the selection of corrugated cardboard to structural design, material use, and processing technology, in order to ensure that the carton has sufficient load-bearing capacity and impact resistance.
