In recent years, with the rapid growth in production and export, China's paper industry has gradually developed into an advanced modern industry. Paper products are divided into four categories according to their use, including household paper, industrial paper, cultural paper and special paper. However, the quality of paper products is uneven, non-conformity products are often found in market supervision sampling.
