Reasonable selection of raw materials and proportioning control
The main raw materials for the domestic production of corrugated base paper are recycled waste cartons, and the quality of recycled waste cartons is often uneven.
The wood pulp in imported waste cartons is generally more, and its fiber strength is better, while the fiber quality of domestic waste cartons is generally poor after repeated reuse.
A large number of domestic waste corrugated boxes are used to produce recycled corrugated base paper, which has become an unavoidable reality. Therefore, the key to producing high-quality corrugated base paper is to carefully select the raw waste paper and use it reasonably with other high-quality waste paper before crushing the pulp in the production process.
