Paper product testing

Challenge:

The paper and paper products industry in China has seen rapid development in recent years and has become a significant player on the international paper industry stage. Due to the widespread adoption of environmental protection concepts, the paper and paper products industry is also keen on innovation, moving towards green technology, energy-saving and low-consumption, pollution prevention, high functionality, and other technological directions. Controlling the quality of papermaking raw materials, improving papermaking technology, relying on high-quality products to establish and enhance brands, and breaking through technological trade barriers in European and American countries are the top priorities for papermaking enterprises seeking further development.
