What raw materials are used to make Folding Box Board?

Hey there! I’m a supplier of Folding Box Board, and I often get asked about what goes into making this stuff. So, I thought I’d take a few minutes to break down the raw materials used in the production of Folding Box Board. Folding Box Board

Wood Pulp: The Foundation

The primary raw material for Folding Box Board is wood pulp. It’s the backbone of the whole operation. There are two main types of wood pulp used: chemical pulp and mechanical pulp.

Chemical Pulp

Chemical pulp is made by cooking wood chips in a chemical solution. This process breaks down the lignin, which is the glue that holds the wood fibers together. The result is a pulp that’s strong and has a high brightness. It’s great for the top layer of the Folding Box Board because it gives a smooth surface for printing. We usually use softwood trees like pine and spruce for chemical pulp. These trees have long fibers that add strength to the board.

Mechanical Pulp

Mechanical pulp, on the other hand, is made by grinding wood chips. This process retains most of the lignin in the wood, which makes the pulp less strong but more cost – effective. It’s often used in the middle layers of the Folding Box Board. We typically use hardwood trees like birch and aspen for mechanical pulp. The shorter fibers in hardwoods help to fill in the gaps between the longer fibers from the chemical pulp, giving the board a more uniform structure.

Recycled Fibers

In addition to virgin wood pulp, we also use recycled fibers in our Folding Box Board. Recycling is a big deal for us because it’s better for the environment and helps to reduce costs. Recycled fibers come from a variety of sources, such as old newspapers, magazines, and cardboard boxes.

When we get the recycled materials, we first sort them to remove any non – paper items. Then, we put them through a pulping process to break them down into individual fibers. The recycled fibers are then mixed with virgin wood pulp to make the Folding Box Board. The amount of recycled fibers we use can vary depending on the quality requirements of the final product. Sometimes, we can use up to 100% recycled fibers for certain types of boards, but for high – quality printing applications, we usually mix them with a certain percentage of virgin pulp.

Fillers and Additives

To improve the properties of the Folding Box Board, we also add fillers and additives during the manufacturing process.

Fillers

Fillers are materials like calcium carbonate and kaolin clay. We add them to the pulp to improve the board’s opacity, smoothness, and printability. Calcium carbonate is a popular filler because it’s inexpensive and can increase the brightness of the board. Kaolin clay, on the other hand, gives the board a nice, smooth surface that’s great for high – quality printing.

Additives

There are several types of additives we use. For example, we use sizing agents to make the board more resistant to water. This is important because if the board gets wet, it can lose its strength and become deformed. We also use strengthening agents to improve the board’s tensile strength and burst strength. These agents help the board to withstand the stresses of folding, gluing, and being filled with products. And then there are optical brighteners that make the board look whiter and brighter, which is especially important for visual appeal in the marketplace.

The Role of Water

Water is another crucial raw material in the production of Folding Box Board. It’s used throughout the manufacturing process, from pulping the wood chips to forming the paper web on the paper machine.

During pulping, water is used to break down the wood into pulp and to transport the pulp through the system. On the paper machine, water is drained from the pulp to form the sheet of paper. The water has to be clean and free of contaminants because any impurities can affect the quality of the final product. We have a complex water treatment system in place to reuse as much water as possible and to minimize our environmental impact.

How These Raw Materials Come Together

Once we have all the raw materials ready, the manufacturing process begins. First, the different types of pulp and fillers are mixed together in a large tank. The consistency of the pulp mixture is carefully controlled to ensure that the final board has the right thickness and strength.

Then, the pulp mixture is fed onto a paper machine. On the paper machine, the water is removed from the pulp, and the fibers start to bond together to form a continuous sheet of paper. The sheet is then pressed and dried to further remove moisture and to improve its strength and smoothness.

After drying, the board goes through a finishing process. This can include calendering, which is a process of passing the board through a series of rollers to make it even smoother. Then, it’s cut and trimmed to the desired size and packaged for shipment.

Quality Control

As a supplier, we take quality control very seriously. We test the raw materials at every stage of the process to make sure they meet our standards. For example, we test the wood pulp for fiber length, strength, and brightness. We also test the recycled fibers to ensure that they’re free of contaminants.

Once the Folding Box Board is made, we conduct a series of tests on the finished product. We check the board’s thickness, strength, printability, and moisture content. If any of the tests fail, we take corrective action immediately to ensure that only high – quality products go out to our customers.
