High-quality, high-operation technical problems of domestic 5-layer corrugated board production line solved

The production of 5-layer corrugated board production line with high-quality and high-speed operation technology has been overcome. The technical problems that have plagued China's packaging industry for many years have been jointly overcome by Wenzhou University and East Packaging Corporation. This study has filled the domestic gap.

After the fall of the high-speed operation technology of five-layer corrugated paperboard in China, Western companies, especially North America, represented by the United States Langston Company and the United States Maguo Company have monopolized the highest level of corrugated board production technology and corrugated board production lines. , And before China's corrugated board production line can only meet the production needs of the general low-grade corrugated board, the overall level of the level of the foreign 50s, especially poor process and operational reliability, cardboard uneven and broken, seriously restricting the overall corrugated board in China The level of improvement. The research team led by Prof. Yang Fuxin, Dean of the School of Industrial Engineering of Wenzhou University, cooperated with the East Economic Commission to carry out experimental research and finally solved the problems that the packaging industry has not been able to solve for a long time.

The project has spent one year of hard work, in-depth production of the first line, understand the production status, analysis of high-speed operation of the corrugated board in the quality of the reasons and mechanism of reduction, comparison of key technical parameters. In researching high-speed operations, we have been making unremitting efforts to find technical solutions to cracking or cracking of the base paper and to eliminate brittle fractures. With the solution of the problem, it is of great significance to drive the industry of the entire packaging industry to increase and decrease the competitiveness of corrugated packaging products in China and reduce the cost and quality. At the same time, this is also a successful example of Wenzhou University's promotion of technical cooperation between universities and enterprises in recent years.
