The production process of corrugated cardboard typically involves the following steps:
- Raw material processing: Forest pulp and recycled paper are processed to remove impurities, pulped, and screened.
- Corrugated medium manufacturing: After the raw material processing, the paper is fed into a corrugating machine, where it is shaped into corrugated medium with wave-like shapes.
- Linerboard manufacturing: Different types of paper are used to create linerboard with smooth surfaces through coating or embossing.
- Corrugated board forming: The corrugated medium and linerboard are glued and laminated together to form corrugated board according to a specific specification.
- Cutting and shaping: The corrugated board is cut and shaped to the required dimensions and shapes based on customer needs.
- Inspection and packaging: The finished corrugated cardboard is inspected for quality, packaged, and transported to customers’ production lines or warehouses for use.
Throughout the production process, corrugated cardboard manufacturers need to control the quality of raw materials, improve production line management, and ensure high-quality corrugated cardboard production to improve production efficiency.
