Kraft paper is a form of paper that is made from pulp. The word "Kraft" means "strong" in German, which explains why it is so enticing to packaging manufacturers.
Kraft paper is made from raw wood fiber, sometimes known as "virgin" pulp. Kraft paper for packaging contains more sulfur than other methods such as recycled paperboard or solid bleached sulfate (SBS). The higher Sulfur concentration prevents cellulose degradation and makes the fibers more durable.
Kraft paper that has not been bleached or coated is dark brown and contains no hazardous chemicals. This type of paper is safe for the environment. Companies, however, use bleaching procedures to generate white pulp from it. Kraft paper is also used to make corrugated kraft cardboard. The cardboard gains layers through the fluting technique, increasing its strength and durability.
Kraft paper, now used as a packaging material, was created by the German Carl F. Dahl in the 1880s using the Kraft pulping method. Dahl discovered that adding specific chemicals (sulfates) to the cellulose pulp increases the paper's firmness. Typically, wood is "pulped" when making paper.
It was originally used as wrapping paper. But later, Kraft paper's resilience and strength made it the perfect material for making packaging items like the recognizable brown cardboard boxes that we are all familiar with today.
Stronger than regular paper is Kraft Paper. More lignin can be extracted from Kraft wood pulp thanks to the previously mentioned Kraft process. More cellulose is left behind by this lignin, which also gives Kraft paper its resistance to tears and durability.
Furthermore, compared to regular paper, raw Kraft Paper Packaging is more absorbent. Although the printing method used on it is somewhat less effective, it is very accommodating to specific finishing techniques like foil stamping and embossing.
Kraft paper is currently most frequently used in corrugated boxes, but carton boxes are also gaining popularity. The e-commerce industry uses these boxes to protect products because they can withstand handling procedures during shipping. After all, Kraft paper is durable.
Businesses frequently use Kraft Packaging Boxes to show off their environmental efforts and achieve sustainability objectives. It is all made possible by the raw, rustic appearance of brown Kraft paper. In the modern packaging industry, Kraft Paper is incredibly flexible and enables a wide variety of inventive packaging ideas.
