The cardboard box is a commonly utilized material for packing. It is a fundamental item in the production of packaging. It is not limited to stocking shelves; it is also evident along the whole supply chain. It is difficult to comprehend that a cardboard box, which is usually decorated and labeled with enticing colors and words, was once a tree. We go over each stage of the box manufacturing process in detail.

As buyers, we frequently overlook the production process of products, but we believe that the packaging is something to be proud of. How then can a tree end up being a box?

The processes involved in making a box

1. the tree

A cardboard box was once a tree, even though we like to use recycled cardboard when making boxes. Softwood woods like fir and pine are typically employed in the box making industry. They are selected because of their long fibers, which can aid in giving the cardboard a nice finish and producing stress, which boosts strength.

A lot of manufacturers will select wood from managed and sustainable forests, which means that any trees that are cut down are replaced in order to preserve the forest’s environment. The type of tree utilized will determine the color of the paper and cardboard that are produced. For instance, spruce produces a light brown color, but silver birch trees yield a dark color.

2. The pulp

Wood chips are produced by felling the tree. After that, pulp is created from these wood chips. This can be accomplished by heating the wood chips chemically or by grinding the wood against a stone. Using this, you may strengthen the pulp by adding substances like sodium sulfate. The pulp of most cardboards is left the same color. To make it seem white, though, it may also be bleached.

3. Corrugation

After the pulp has dried, you may begin making cardboard. Two pieces of paper or card called liners and a piece of fluted cardboard to place in between the liners are needed for corrugated cardboard. Fluting contributes to the cardboard’s increased strength and level of damage resistance.

Paper created from the dry pulp is run through a corrugated roller, which gives the paper a fluted or ruffled appearance. The amount of fluting needed will depend on how well the box is constructed. This is utilized for high-quality boxes because it increases the fluting, which increases the amount of material used and, consequently, strength. When it comes to less expensive boxes, using less fluting can help save space, use less material, and emit less carbon dioxide.

The flutes are made by the corrugation machine using hot steam. In order to make the flute attach to the liners, glue is simultaneously rolled down each side of the flute. After corrugated cardboard is created, straight edges are added by trimming it.

4. Cutting

After completing the corrugated cardboard, cut the card to the appropriate size based on the specifications of the box. A thorough instruction manual is provided, and many of the machines are set up to automatically cut cardboard to the desired size based on manufacturing need. After cutting the card’s basic outline, it is transported to a trimmer.

The trimmer is made to handle complex elements that the cutting machine is unable to manage. A trimmer may cut the flaps required to assemble the box and add handles to it. When the box is ready for assembly, folding will be simpler thanks to the trimmer’s additional scoring of the cardboard.

5. Assembly

Assembly will be based on the box’s specifications. For businesses that wish to build their boxes as needed, using flaps and slots can be the ideal option. In addition to this, tape-built boxes are frequently effective to assemble when needed. Stronger boxes are typically kept together by folding pieces together and sewing them together.

On demand, certain cutting-edge machines can build boxes for you. An example of an on-demand box maker is Ribble Right Size. In order to minimize waste and guarantee the greatest fit, it calculates the ideal size box based on your requirements. Because the box is built specifically for you, packaging manufacturing time may be greatly lowered.

Offcuts from assembly can be recycled to keep the box-making process going. The boxes may be recycled to start a never-ending cycle of recycled box production once they have been branded, printed, and used.
