Corrugated boxes are made of corrugated cardboard, they are the most widely used paper packaging containers, especially often used for transportation packaging. Corrugated boxes are widely used because they have many unique advantages:
①Good cushioning performance. Corrugated cardboard has a special structure, 60~70% of the volume of the cardboard structure is empty, so it has good shock absorption performance, which can avoid collisions and impacts on the packaged items.
② Lightweight and firm. Corrugated cardboard is a hollow structure, and uses less materials to form a more rigid box, so it is light and firm. Compared with a wooden box of the same volume, it is only 1/4 to 1/5 of the weight of the wooden box.
③Small size. When storing and transporting, the corrugated box can be folded into a flat shape, which is convenient for storage and transportation; when in use, it can be opened into a box, and the volume is much smaller than that of wooden boxes and plywood boxes of the same volume.
④Sufficient raw materials and low cost. There are many raw materials for the production of corrugated board, such as corner wood, bamboo, wheat straw, reed, etc., so its cost is lower, only about half of the same volume of wooden boxes.
⑤ It is convenient for automated production. A complete set of corrugated box production automatic line has been manufactured, which can produce corrugated boxes in large quantities and with high efficiency.
⑥The packaging operation cost is low. Packing items in corrugated cartons makes it easy to achieve automated packaging of items, which reduces the packaging workload and reduces packaging costs.
⑦Can pack a variety of items. The corrugated box itself has a wide range of packaging items, but if combined with various coverings and moisture-proof materials, it can greatly expand the scope of use. For example, moisture-proof corrugated boxes can pack fruits and vegetables; corrugated boxes covered with plastic film can be packaged and easily absorb moisture Items; plastic film bushings are used to form a sealed package in the box to pack liquid, semi-fluid items, etc.
⑧The amount of metal is small. The forming of corrugated boxes requires only a small amount of box nails, which is only 5% of it compared with the manufacture of wooden boxes.
⑨Good printing performance. Corrugated cardboard has good ink absorption capacity, is easy to print, and is easy to advertise products.
⑩Can be recycled and reused. Corrugated boxes can be reused many times, which reduces packaging costs and does not pollute the environment.
