The characteristics of corrugated paper boxes mainly include the following aspects:

Lightweight and sturdy: Corrugated cardboard is a hollow structure that uses fewer materials to form a rigid box, making it more lightweight and sturdy than similar cardboard boxes.

Good cushioning performance: Due to the special structure of corrugated cardboard, 60-70% of the volume in the cardboard structure is empty, which has good shock absorption performance and can prevent the packaged items from being collided and impacted.

Sufficient raw materials and low cost: There are many raw materials used to produce corrugated cardboard, such as corner wood, bamboo, wheat straw, reeds, etc., so the cost is relatively low, only about half of the same volume of wooden boxes.

Easy processing: The production of corrugated cardboard boxes can achieve a high degree of mechanization and automation, and packaging operations for products can also achieve mechanization and automation.

Convenient storage and transportation: Empty boxes can be folded or unfolded for transportation and storage, making it easy to load, unload, and stack, saving effective space for transportation vehicles and warehouses, and improving their efficiency.

Easy to automate production: A complete set of corrugated cardboard box production automatic line has been manufactured, which can produce corrugated cardboard boxes in large quantities and with high efficiency.

Wide application range: Corrugated cardboard boxes have a relatively large range of packaging items, and if manufactured separately with various coverings and moisture-proof materials, their application range can be greatly expanded.

Low metal usage: The forming of corrugated cardboard boxes only requires a small amount of box nails, which is only about half compared to the manufacturing of wooden boxes.

Reusable: Corrugated cardboard boxes can be reused multiple times, reducing packaging costs.
