[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and their usage has always been the first among various packaging products, including calcium plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. Die-cutting machines are required in the production process of corrugated boxes.
