Kraft Packaging – A Complete Guide
What is Kraft Packaging?
Kraft packaging is a type of eco-friendly packaging made from kraft paper, which is known for its strength, durability, and recyclability. It is widely used in food, cosmetics, retail, and shipping industries because of its natural brown color and eco-friendly appeal.
Most people need clarification on this term and a search to see if cardboard material is made of paper. Yes, it is made of paper but not the same as normal paper. It is a type of paper product that is thicker and more rigid than standard paper. This flexible material is versatile enough to be cut and folded into different shapes and sizes to suit the needs of the product. Its manufacturing process includes many steps, beginning with the fibers’ pulping and then through multiple stages of pressing and molding.

Paperboard is constructed by layering pulp and spraying water onto a mesh screen to create a mat. This process builds up the pulp fibers, strengthening the paperboard. Each grade of paperboard is carefully blended to meet specific standards.
Once the mat is formed, excess water must be removed. Initially, 20% of the water drips through gravity as the mat passes over a foundation screen. The mat then moves through sponge rollers to press and squeeze out water further. The mat is stretched and heated to complete the drying process, reducing the moisture content to 5%.
The dried paperboard is then cut into various widths and rolled into large rolls for transportation to box manufacturers. These widths enable the production of boxes in multiple sizes, shapes, and configurations to meet customer requirements.
After the layers of cardboard are assembled, they undergo a crucial step known as bonding and drying. This process is essential for ensuring that the layers firmly adhere to each other and that any excess moisture is eliminated.
First, the assembled cardboard passes through a series of heated rollers or drying chambers. These rollers or chambers provide controlled heat, which activates the adhesive properties of the materials used in the cardboard layers. As a result, the layers bond securely, forming a unified and sturdy structure.
Additionally, the heat applied during this process evaporates any remaining moisture in the cardboard. Excess humidity can weaken the cardboard and compromise its structural integrity. Removing this moisture makes the cardboard stronger, more rigid, and better suited for its intended purpose.
Overall, the bonding and drying stages are crucial for ensuring that the cardboard is of high quality and ready for further processing or packaging. It plays a vital role in creating cardboard products that are durable, reliable, and able to withstand the rigors of transportation and handling.
The end of this process is to assemble the sheets of cardboard paperboard into the desired shapes and sizes of boxes for the intended use. It may include cutting, scoring, creasing to make folds easy, and printing to make the boxes attractive.
