But what makes kraft paper so special? Let’s explore its unique features, types, benefits, and the many ways it’s used. Discover why this paper is leading the way in sustainable packaging.
What Makes Kraft Paper Unique?
Kraft paper gets its name from the German word ‘kraft,’ meaning strength, which describes its tough and tear-resistant nature. It usually consists of unbleached wood pulp. The traditional color of this paper is brown. However, due to advancements in the processes, white kraft paper has also been produced by bleaching. The brown one contains wood pulp, especially from softwood trees, including pine and spruce trees. This makes it a renewable and more durable resource in an ecological concern.
The beginning of invention of kraft paper goes back to the end of the 19th century when Carl F. Dahl discovered the kraft pulping process. This paper goes through a different kind of pulping in comparison with other types. In that type of pulping process, more lignin has to be extracted, so greater concentrations of cellulose would remain there. Just that makes this paper so strong, tough, and a material of the very popular idea of packaging known as sustainable packaging.
Now that we understand what kraft paper is, let’s see how it’s made.
How is Kraft Paper Made?
In the making of this paper, the chips derived from both softwood and hardwood are utilized. Preparation for manufacturing starts by pre-steaming the chips inside a steaming vessel. Next, chips are pulped by the kraft process, which is called “Kraft Pulping” or the “Sulfate Process.” Chips are cooked with a mixture of hot water, sodium hydroxide (NaOH), and sodium sulfide (Na₂S) inside large pressurized digesters. This chemical mixture in water dissolves the lignin from wood and leaves strong and flexible cellulose fibers.
When the pressure is released to a blow tank, the chips break apart into unbleached pulp fibers. The brown stock washing stage removes residual chemicals and recycles them. In this process, about 90% of the chemicals can be recovered and reused. The pulp may then be bleached to a bright white color in the bleaching plant.
After bleaching, the pulp is blown into a slurry and sprayed onto a machine screen. Then, pressed and dried in the dryer section. The dried pulp is cut and baled into large bales.
Kraft paper can be modified to various needs. So this paper has different types for different uses. Let’s look at some of the types and their applications.
Types of Kraft Paper
Kraft paper comes in various forms to meet different needs:
- Natural Brown Paper
Brown Kraft paper has retained its natural color and gives an environmentally friendly appearance. Common uses of this paper are wrapping, crafting, and heavy packaging. This is the commonly used type where strength and simplicity are key.

This type of paper undergoes an extra process to produce a clean, white look. Due to the bleaching process, it is slightly less environmentally friendly. It is used in premium packaging where gorgeous looks are important.
- Recycled Paper
It is made from post-consumer waste. This paper is a great alternative for companies that want to maintain sustainability. Although not much stronger than virgin kraft paper, recycled kraft paper retains its core characteristics and is ideal for sensitive products.
- Moisture-Resistant Paper
Coated kraft paper is treated with materials such as waxes or polyethylene. Therefore, this type does not allow moisture and greases to pass through. Its use in food packaging and wherever durability against outside elements is required is common.
