How Cardboard Boxes Are Made?

The boxes that we take for granted nowadays are Cardboard Boxes. You have no idea how versatile these boxes are from cosmetic products to kids’ commodities. Indeed, these boxes have long been used for shipping different purposes. 

Being a packaging manufacturer, we understand that you might be stressed about your goods’ safety when they get dispatched to the market. Here, good quality packaging comes in with its crucial role. This is why cardboard box production has increased rapidly for businesses’ convenience and safety requirements.

The final face of the boxes that everybody, comes after going through numerous production phases. Well if you are wondering how they were made then read further to reveal the secret of making cardboard boxes. 

The First Basic Step – Recycling

Every final product that we used today, goes through a different process. Just like that, cardboard box factory also goes through a different process to provide individuals with the fine-quality product. 


A cardboard box is made up of recycled paper. This process is also called flute in this step the recycled paper is sandwiched between two liners. It is now very usual for these liners to also be made up of a substantial proportion of recycled content, sourced from previous boxes or other sources of next-hand paper.

However, for the best quality boxes virgin Kraft paper is still used in making. In the actual process, it doesn’t matter whether the virgin paper is properly recycled or not, because it always started as virgin kraft paper which is made from natural resources (trees) that have been pulped. 

Second Step – The Trees

During production, boxes go through two various types of liners, this is the material that lies on the top part and beneath the fluting which helps to create a corrugated board. Typically, these boxes have a test paper which is called an inner liner, and the outer covering called Kraft paper. This is because Kraft is the best quality than test, the good thing about this paper is that it has a smoother finish so that it can be conveniently printed on. Kraft paper also has the benefit of being resistant to water infiltration which is an additional benefit of using it.

In cardboard box production fine quality Kraft paper is used because it is made from softwood trees and has long fiber. Long fibers are also better decisions which are why Kraft paper is often mentioned as having a high tear and burst resistance. The names of trees that have softwood are pine, spruce, and fir.  

Test paper liners are normally made of hardwood from trees that have short fibers, or recycled paper. Moreover, Kraft and Test paper are commonly used in making to create the fluted paper in between liners which help to create a strong board. 

Third Step – The Pulping

To create a good quality paper a long process is involved in the background. The producer always ensures that the wood chips that are pulped are clean and suitable for more processes. The process starts with the trees which are cut and clumped to create millions of logs that go through a huge machine to be disbarked and chipped. 


These chips are put all together in one process typically mechanical pulping or chemical pulping have been used. Mechanical pulping is normally focused on grinding which helps to reduce wood to individual cellulose fibers by forcing the debarked wood bars against a revolving stone to make a pulp. Chemical pulping helps to reduce the raw material in cellulose fiber. 

Fourth Step – Fluting

The fluted boxes are wavy pieces of board. It is sandwiched between the liners which give a box a precise shape and strength. The good thing about this box is, it protects the boxes from knocks and impact damage. To create the fluted effect, paper is fed into a roller machine. 

Fifth Step – Production

In the fifth step of production, the paper goes through a corrugator, in which hot water is sprayed on the kraft paper which allows it to be pressed, and another roller glues one side of the flute. The two liners in this process are adhered to the board by the machine so the cardboard is cut precisely from each side with a circular saw to give the board equal sides. The cutting machine cut the board more than five times but it depends on the size of the box. 

Once the cardboard has been cut the corrugator separates the boards into layers and stacks them into pack quantities that are ready to be fed into the trimmer. Then, the bending machine folds the boxes, and glue is applied to them which will come together to form the box. So, after the process, the final product is ready to dispatch.
