The cardboard box is one of the most commonly used packaging materials. It is deemed as a core product in packaging manufacturing. It doesn’t only fill the shelves but can be easily seen in the entire supply chain as well. When you look at a cardboard box by http://belley.net/ which is typically printed and branded with alluring colors and words, it can be hard to imagine if it began the life as a tree. This article enlists the box manufacturing process step by step. Everyone celebrates the product but never its packaging. So let’s do this by discussing the steps on how a box is made.
- Tree
When you look at a recycled cardboard box when it comes to its production, know that it began its life as a tree. Usually the trees used for box manufacturing are the softwood trees like pine and fir tree. The reason they are selected is that they consists of long fibers that can help in creating a smooth finish for the cardboard and building tension which helps in strengthening its strength. Many manufacturers will prefer wood from sustainable and managed woodland. In other words, any trees that were cut are replaced in order to manage the ecosystem of the forest. The obtained paper and cardboard made will have a different coloring on the basis of the tree used. For instance, silver birch tree will give a dark color and spruce will give away a light brown color.
- Pulp
When the tree is fell, the wood chips are made. Then they are broken down into pulp. This is accomplished by grinding the wood against a stone or by adding chemicals like sodium sulphate for increasing the strength of the pulp. For most cardboard the pulp is of the same color but it can also be bleached to make it look white.
- Corrugation
Once you have dried the pulp, then start making cardboard. When it comes to making corrugated cardboard, you need two pieces of paper called liners and a part of fluted cardboard which is installed between the liners. Fluting helps in strengthening the cardboard. The paper rolls made from dried pulp are fed via a corrugated roller which flutes or ruffles the paper. On the basis of the box quality, it will determine the level of fluting needed. When you increasing the fluting, you increase the strength which makes it a high quality product. For cheaper boxes less fluting is used.
- Cutting
Now the card is cut to size on the basis of the box needs. Here many machines are programmed to cut the cardboard for scaling automatically on the basis of the production demand. Once the outline has been cut, then the card is trimmed. It also helps in adding handles to boxes. Then the box is sent for finishing.
