Case Studies
Your Trusted Partner in Valve Bag Making Machinery

Suzhou Yideng Machinery Company was established in 2001, focusing on the research, development, and manufacturing of equipment and production lines required for paper sack bags. The company primarily serves industries such as construction materials, chemicals, and food packaging.

At the beginning, the company mainly imported second-hand valve bag production lines from Europe and the United States for refurbishment and upgrading services. After 20 years of technical research and experience accumulation, in 2020, we developed the paper valve bag bottomer machine with independent intellectual property rights in China, with a production speed of 200 bags per minute and a design service life of 20 years.
