[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 have always been the most used 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 properties, becoming the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products. They are beneficial to the environment and easy to load and unload. In the production process of corrugated boxes, corrugated cardboard needs to be cut.
