Beijing Corrugated Box Factory

In our daily lives, whether it's for shipping or packing items, we can't do without cardboard boxes. But do you know what the raw material for cardboard boxes is? The raw material used by cardboard box factories is pulp (made from materials like reeds, straw, and wood, which are cut into strips for chemical pulp production or wood chips for mechanical pulp), and then these small pieces are placed in a digester with chemical liquids, cooked with steam to turn the materials into pulp.

Here's a bit more about cardboard: Pulp is a fibrous material made from plant fibers through various processing methods. It can be categorized into mechanical pulp, chemical pulp, and chemical mechanical pulp based on the processing method, or into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, and rag pulp based on the fiber source. It can also be classified into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, and semi-chemical pulp according to purity levels. Generally, it's used for making paper and cardboard. Refined pulp, in addition to being used for special papers, is often a raw material for producing cellulose esters, cellulose ethers, and other cellulose derivatives. It's also used in artificial fibers, plastics, coatings, films, and more.
