Corrugated cardboard box is a commonly used packaging material, which is widely welcomed for its excellent compression resistance and environmental friendliness. Its main production process includes the following steps:

1. Raw material preparation: High quality cardboard and carton paper are selected for production. These raw materials need to be cut according to the specifications and requirements of the cartons for the subsequent production process.
2. Printing process: Printing process is carried out on the cardboard according to the customer's requirements. This step includes the printing of patterns, text, barcodes and other information.
3. Corrugating: The single layer of paperboard is formed into a corrugated shape by processing equipment to enhance its structural strength. Common corrugated shapes include U-type, V-type and E-type.
4. Carton Forming: The processed cardboard is laminated and folded to form the various parts of a carton. This step also requires appropriate size adjustments and shape corrections.
5. Assembly and sealing: The formed carton parts are assembled together and sealed by a sealing machine to ensure the integrity and stability of the carton.
6. Quality Inspection: Conduct quality inspection on the produced corrugated cartons to ensure that each carton meets the specifications and quality standards. The inspection includes appearance, size, compression resistance, etc. 7. Packing and Storage: The quality check is carried out to ensure that each carton meets the specifications and quality standards.
7. Packing and storage: The quality-checked corrugated cartons are packed and stored in the warehouse for subsequent shipment or sale.
8. Post-processing: According to the needs of customers, the corrugated boxes undergo other post-processing, such as punching, labeling, and marking.

Throughout the process, production personnel need to pay close attention to the details of each step to ensure that the corrugated boxes produced are of stable quality and excellent performance. In addition, in order to reduce production costs and improve production efficiency, the production process also requires reasonable equipment selection and process optimization.

Overall, the production process of corrugated boxes is a complex and rigorous process that requires the production staff to have a wealth of experience and skills. With the development of science and technology, the production process of corrugated boxes is also progressing towards automation and intelligence, in order to improve production efficiency and product quality. The above is the main production process of corrugated boxes.
