What is Kraft Paper?

The term Kraft in Kraft paper is taken from the German word Kraft, meaning strength, which is a strong and hardy paper manufactured by kraft pulping. This is a process where wood fibres are treated chemically, hence creating a tear-fiber, flexible paper which is commonly used in packaging applications. It is naturally brown in colour since the wood pulp is minimally bleached to provide the rustic and deep colouring. Kraft paper contributes to packaging popularity because it is reusable, versatile and sturdy. At PaperBox Packaging, we offer high-quality, sustainable Kraft paper packaging ideas and solutions to businesses.

What is the Process of making Kraft Paper?

The production of Kraft paper involves a chemical pulping method that dissociates cellulose fibres and removes them from wood, mostly pine (softwood). The reaction of the breakdown of these lignins is then treated in sodium hydroxide and sodium sulphide to extract the lignin, which is used to give strength to the paper. The outcome is a thick, solid paper that is highly durable. Bleaching may be done to some varieties of kraft paper to render it white or even feather white.

Types of Kraft Paper 

There are three types of Kraft paper, such as:

1. Coated Unbleached Kraft Paper (CUK): 

It is the simplest of all types of kraft paper, which was produced without bleaching. It is very tear-resistant and creates good packaging solutions that are durable.

2. Solid Bleached Sulphate (SBS): 

Bleached Kraft, servicing high-end products, is smooth and of better quality in printing and high-quality appearance.

3. Coated Recycled Board (CRB): 

CRB has an excellent green profile, as it is made with recycled components, but still has high tensile strength and can be used as an alternative to the virgin kraft paper in certain types of package demands.

At PaperBox Packaging, we have many varieties of the different types of kraft paper, such as paper pulp box and custom paper bags, to meet your special needs in packaging.
