Corrugated boxes are widely used paper containers for packaging and are widely used for transportation. The reason why corrugated boxes are widely used is that they have many unique characteristics.
1. Good cushioning performance. Because corrugated cardboard has a special structure, 60-70% of the volume in the cardboard structure is empty, so it has good shock absorption performance and can prevent the packaged items from collision and impact.
2. Stability. Corrugated cardboard is a hollow structure, which uses less material to form a rigid box body, so it is more stable than similar cartons, and compared with wooden boxes of the same volume, it is only about half the weight of wooden boxes.
3. Smaller volume. Corrugated boxes can be folded into a flat plate during storage and transportation. When used, they can be opened to form a box body, and the volume is much smaller than wooden boxes and plywood boxes of the same volume.
4. Adequate raw materials and low cost. There are many raw materials for producing corrugated cardboard, including corner wood, bamboo, wheat straw, reeds, etc., so its cost is low, only about half of the same volume of wooden boxes.
5. Easy to automate production. Complete sets of automatic corrugated box production lines have been manufactured, which can produce corrugated boxes in large quantities and with high efficiency.
6. Wide range of applications. The range of corrugated boxes themselves for packaging items is relatively large. If they are manufactured separately with various coverings and moisture-proof materials, the scope of application can be greatly expanded. For example, moisture-proof corrugated boxes can be used to package fruits and vegetables; plastic film coverings can be used to package moisture-absorbing items; plastic film liners can be used to form sealed packages in the box to package liquids and semi-fluid items.
7. Less metal usage. The molding of corrugated boxes only requires a small number of box nails, which is only about half of that of wooden boxes.
8. Can be reused. Since corrugated boxes can be reused many times, the packaging cost is further reduced.
