瓦楞纸箱生产工艺流程英文版
The corrugated cardboard production process involves several steps that are necessary to manufacture corrugated cardboard boxes. Corrugated cardboard boxes are widely used for packaging purposes across various industries. The following is a general description of the production process.
1. Paper preparation: The first step in the production process is the preparation of paper. This involves selecting the appropriate types of paper to make the corrugated cardboard. The most common papers used are kraft linerboard and medium paper.
2. Corrugating: In the next step, the medium paper is passed through a corrugating machine, which adds fluting to one side of the paper. The fluting is responsible for the strength and rigidity of the final corrugated cardboard.
3. Adhesive application: To create the corrugated cardboard, the corrugated medium paper is glued to the kraft linerboard. Adhesive is applied to the flutes of the medium paper, which are then pressed onto the linerboard.
4. Molding and drying: After the adhesive application, the glued paper is passed through a set of heated rollers. The heat helps in the drying process and ensures that the adhesive is properly bonded with the linerboard.
5. Cutting and scoring: Once the corrugated cardboard sheet is dry, it is cut into large sheets of standardized sizes. This cutting process is typically done using a high-speed rotary cutter. In addition to
cutting, the sheets are also scored to create fold lines for easy assembly.
6. Printing and die-cutting: At this stage, the large sheets of corrugated cardboard can be printed with designs, logos, or product information using a flexographic printing process. After printing, the sheets can be die-cut into specific shapes and sizes using sharp metal dies.
7. Box assembly: The die-cut corrugated cardboard sheets are then folded and glued to form the desired box shape. This assembly process can be done manually or by using specialized machines for higher volumes.
8. Quality control: Throughout the production process, quality checks are performed to ensure that the corrugated cardboard meets the required standards. These checks include measuring the strength, thickness, and overall durability of the boxes.
9. Packaging and distribution: After passing the quality control checks, the finished corrugated cardboard boxes are packaged and prepared for distribution. They are often stacked and secured on pallets for easy transportation.
The above steps provide a general overview of the production process for corrugated cardboard boxes. It is important to note that specific details and variations may exist depending on the manufacturer and the intended use of the boxes.。
