Corrugated cardboard boxes are a commonly used packaging material, typically made up of three layers of cardboard, with a corrugated layer in the middle and flat layers on the outside. The main principle of corrugated cardboard boxes is to utilize the cardboard’s bending strength and the corrugated layer’s wave-like structure to enable the box to withstand external forces and protect the contents inside.
The wave-like structure of the corrugated layer can enhance the box’s compression strength by dispersing external forces along the wave-like structure, thereby avoiding force concentration at a single point that could cause the box to break. Additionally, during the manufacturing process of corrugated cardboard boxes, the corrugated layer is sandwiched between two flat cardboard layers and glued together, creating a stable three-layer structure that also enhances the box’s strength and stability.
The manufacturing process of corrugated cardboard boxes includes the production of corrugated cardboard, printing, and cutting. Corrugated cardboard is typically made from pulp through processing, pressing, and drying processes. Different manufacturing techniques and materials can affect the strength and quality of corrugated cardboard. The printing and cutting processes involve the use of printing and automatic cutting machines, which can customize the boxes by printing logos and cutting them into different shapes and sizes.
