How Corrugated Cardboard is Manufactured

Corrugated cardboard boxes make up most of the materials that are transported to us. These arrive safely, without damages, and still intact. If these materials are raw goods or food, they come to us fresh and ready for consumption. Cardboard box manufacturers make this happen when it comes to material transport.

Have you ever wondered how this corrugated cardboard is made and manufactured to transport products? Here’s a quick run through on how the manufacture of corrugated cardboard boxes goes:

Raw Materials

First, the finest raw materials are collected to create corrugated cardboard. Fast-growing pine trees are the primary material used to make the cardboard. The pine tree wood chips are mixed with other materials, such as cornstarch glue and water to stick the pulp together. Different types of materials used for labeling are certain types of dye. Paraffin or vegetable oil can also be used by cardboard box manufacturers to ensure an added layer of water resistance.


Once the pulp of raw materials is combined, a paper-making machine called takes the pulp in. This machine creates the paper, after which the paper undergoes an additional process to remove excess water. Excess water is removed by placing the paper in steam-heated rollers to flatten them out.

Quality Control

Once the paper has been formed, dried, and cleaned out, it also undergoes quality control. Quality control is a crucial step done by cardboard box manufacturers to determine the reliability of their finished product. These cardboard products are subjected to several tests involving their bursting strength, compression, and how well the materials will fit in the box. All of these are necessary to ensure only the best quality of cardboard box is produced for users.
