The corrugated case is a packaging product with the widest application, and the use amount is always the first of various packaging products. Comprises a calcium plastic corrugated case. For more than half a century, corrugated cartons gradually replace transport packaging containers such as wooden boxes and the like with excellent service performance and good processing performance, and become the leading force of transport packaging. It not only protects the goods, is convenient for storage and transportation, but also beautifies the goods and publicizes the goods. The corrugated case belongs to green environmental protection product, and it does benefit to the environmental protection, does benefit to the loading and unloading transportation. Corrugated board means that a middle layer extending in a wave shape is arranged between two outer covering surfaces, so that compared with common hard board, the corrugated board has better structural strength. Existing cartons include a carton body having at least four walls and a bottom, and a lid. The four walls of the box body are respectively composed of four corrugated boards, and the edges of the four corrugated boards are folded together to form a bottom surface. The cover can be a separate cover or the same structure as the bottom.

Current corrugated box is folding along its juncture of four walls usually at folding process, and folding back area that occupies on the plane is great, is not convenient for carry the transportation to current corrugated box is at the in-process that uses, and it brings the packing to need to use glue usually, unpacks once more after the sticky tape packing and can lead to the box to receive destruction, leads to corrugated box can't use once more, has caused the waste on the resource.
