PRODUCTION OF PULP AND PAPER

All our products are made from previously used paper, thus giving the paper a new life. The raw material mainly comes from Estonian packaging and printing industries, retail, and environmentally conscious individuals.

Production begins with the preparation of paper pulp in two special shredders called pulpers. Various types of waste paper and water are added into the pulpers; when mixed, a paper pulp with 3–4% fiber content is obtained. Foreign materials (plastic, tape, sand, metal) are then removed from the pulp, and the paper fibers are ground in special refiners.

The pulp preparation process is very important in papermaking because it determines the composition of the paper, which is essential for producing high-quality products.

The process continues in the paper machine. In a special tank, the pulp is diluted to 0.8–1.5% fiber content and poured onto a moving wire screen to form a paper web. The pulp is shaken on the wire to achieve uniform strength. Using vacuum pumps located under the wire, water is removed from the pulp until the paper web reaches approximately 20% dry matter content.

The formed paper web is pressed in two stages: first, water is pressed out in the first press; second, the web is pressed in a rotary press to reach about 40% dry matter content.

In the final stage, the paper is dried in the drying section of the paper machine by steam-heated rotating cylinders. The paper web is then given its final smoothing through calendering, and finally, the paper edges are trimmed and the finished product is wound into rolls weighing up to 1500 kilograms.

Räpina paper factory produces paper and cardboard with grammages ranging from 180 to 540 g/m². Modern computer-based technology significantly increases production efficiency and quality.

PRODUCTION OF EDGE PROTECTORS

For the production of edge protectors, we use only cardboard made from recycled paper. By using only cardboard from our own mill, we have full control over the uniformity of product quality.

Large cardboard rolls are first cut into narrow rolls, called bobbins, which are then used in edge protector production lines. A starch-based adhesive is applied between the cardboard layers, and the layers are laminated. The edge protectors are then formed and pressed, cut to the customer's specified dimensions, and finally packed onto pallets.

Stable-quality cardboard, top-level lamination technology, modern high-end equipment, and experienced operators ensure consistently high product quality.
