How is Kraft Paper Made?
The popular kraft paper takeaway lunch box is typically made from a type of kraft paper that has been specially treated for food packaging. Here’s a general overview of how this type of kraft paper is made:
The first step in making kraft paper is to create wood pulp by breaking down wood chips or recycled paper fibers in a process called pulping. For food packaging, only virgin pulp or recycled pulp that meets food safety standards can be used.
The pulp is then cooked to help separate the fibers and create a stronger paper.
After cooking, the pulp is washed and bleached to remove any remaining impurities and brighten the color of the paper.
The pulp is then formed into sheets of paper by pouring it onto a moving mesh screen or cylinder. As the pulp moves through the screen or cylinder, excess water is removed and the fibers begin to bond together.
5. Drying and Finishing:
The paper is then dried and finished, which involves cutting it into the desired size and shape, and adding any necessary coatings, such as a moisture barrier coating, to make it suitable for food packaging.
6. Box Manufacturing:
The kraft paper sheets are then folded and glued together to create the final takeaway lunch box shape.
