The corrugated structure of corrugated box color box has an exquisite design and unique mechanical principle in bearing pressure in different directions.
The corrugated shapes of corrugated board mainly include U-type, V-type and UV-type. Among them, U-type corrugation has good elasticity and buffering performance. When subjected to lateral pressure, its rounded arc can effectively disperse the impact force, just like a spring, evenly distributing the pressure on the entire corrugated structure to avoid local excessive force and damage to the carton. V-type corrugation has higher stiffness and compressive strength. When stacked vertically, its sharp corrugation angle and larger corrugation height can better support the weight above, and transmit the pressure to the bottom of the carton along the corrugation direction, ensuring that the carton has excellent compressive resistance in the vertical direction. UV-type corrugation combines the advantages of U-type and V-type, and can perform well under pressure in different directions.
In the design of multi-layer corrugated board, the corrugation directions of different layers are arranged perpendicular to each other. For example, the common double corrugated cardboard consists of a layer of longitudinal corrugation and a layer of transverse corrugation. When the carton is subjected to vertical pressure, the longitudinal corrugation mainly bears the weight and transfers the pressure to the bottom of the carton; when subjected to transverse pressure, the transverse corrugation plays a role, resisting external forces through its own elasticity and strength to prevent the carton from being squeezed and deformed. This cross-arrangement method greatly improves the carton's ability to withstand pressure in different directions, allowing the carton to maintain structural stability in all dimensions.
In addition, the density and height of the corrugation also play a key role in bearing pressure. Higher corrugation height and appropriate density can increase the buffer space and support force of the carton. When facing a large impact force, the high corrugation can first absorb energy through its own deformation, and then evenly distribute the remaining force to the entire cardboard structure. Reasonable density ensures that there are enough support points between the corrugations to avoid the overall failure of the carton due to local weakness.
At the same time, the bonding process of corrugated cardboard with face paper and lining paper is also crucial. Strong bonding can make the whole structure form an organic whole. When under pressure, each layer of material works together. The face paper and lining paper can protect the corrugated core paper from damage, and the corrugated core paper provides the main compression resistance and buffering functions, thereby ensuring that the corrugated box color box can effectively resist pressure from different directions in complex logistics transportation and storage environments, and protect the safety and integrity of the internal products.
