In recent years, kraft paper has gradually become the preferred paper for many industries due to its excellent physical strength, diverse functional characteristics, and low environmental impact. It is worth mentioning that its 100% recyclable environmental characteristics have received widespread attention.
Definition and Characteristics of Kraft Paper
Kraft paper, with its unique craftsmanship and properties, has occupied a place in the field of paper. It is made from chemical pulp as raw material and processed through a special cowhide pulp process, thus possessing excellent physical strength and diverse functional characteristics. The color of this paper is yellow brown, with a tough and water-resistant texture and excellent tear resistance. In addition, cowhide pulp has a darker color than other wood pulp, but after bleaching treatment, it can be made into very white pulp. In the process of manufacturing high-quality paper, such as fully bleached kraft pulp, its strength, whiteness, and resistance to yellowing are crucial indicators.
Comparison between kraft paper and regular paper
Someone may ask, what is the difference between kraft paper and regular paper? In short, kraft paper is more durable and sturdy. This is thanks to its unique manufacturing process, which allows the wood components to be fully stripped from kraft paper pulp, leaving more fibers and endowing the paper with excellent tear resistance. In addition, although the porous properties of primary kraft paper are slightly inferior to ordinary paper in terms of printing effect, it is very suitable for certain special processes such as embossing and hot stamping.
Application of kraft paper in packaging field
Nowadays, kraft paper plays a crucial role in the packaging industry, especially in the production of corrugated cardboard boxes. Meanwhile, it is also widely used in various types of paper bags, such as cement, food, chemicals, consumer goods, and flour bags, all of which are made of kraft paper without plastic hazards.
