However, the domestic waste paper raw materials far cannot meet the raw material demand of the current papermaking industry, and the raw material gap will reach more than 30 million tons. To solve the problem of insufficient raw materials, foreign waste paper raw materials are pretreated for impurity removal overseas, processed into a fibrous state to meet the national environmental protection requirements, and then packed before being allowed to be imported into the country.
