Kraft Paper Making Line

What Is Kraft Paper?

Kraft paper machines are categorized into kraft paper machines, corrugated paper machines, paperboard machines, etc. according to the type of paper produced.

Kraft liner board machine use waste paper,white shavings ,virgin pulp as material to make high quality Kraft paper board. Finished products can be made paper roll.

Pulp Turned Into Paper

1. Forming dehydration

Dispersing the pulp evenly is an important part of turning the pulp into paper that meets the requirements of use, this needs to dilute the pulp to a consistency of 0.3%~1% to make the fibers more evenly dispersed, and then sprays the pulp evenly onto the forming wire through the headbox, and dehydrate through the gravity and vacuum of the wire part reach 20 % dryness.

2. Press dehydration

Paper sheets with a dryness of about 20% need to be squeezed by press rollers to further remove moisture. Generally, they will go through 2~3 times of pressing to reach a dryness of about 50%.

3.Forming dehydration

After the initial pressing and dehydration, in order to allow the water to evaporate quickly, it needs to be dried by high-temperature steam, and the high-temperature steam is sent into the steel roller (drying cylinder), and the surface temperature of the drying cylinder is transferred to the wet paper sheet, so that the paper sheet Moisture drops below 10%.

4. Rolling

The last step in the utilization of waste paper is to roll the paper into a roll with a roller using friction force, and then produce different types of paper according to different needs.

5. Finished product

The processing plant will purchase base paper for processing according to the end use, These papers will be processed into cartons, packaging bags, packaging boxes, etc. used in daily life through different processing methods such as printing, coating, laminating, bronzing, die-cutting, and box-gluing.
