Cardboard fast food boxes are made of 300-350 grams of bleached kraft wood pulp cardboard as raw materials, and are made by die-cutting bonding or die-cutting pressing, shaping and other processes through a stamping process similar to sheet metal processing.

In the process of production and use, it is non-toxic and has no side effects to the human body. However, the quality requirements for cardboard are higher, and the cost is also increased.
