The paper manufacturing process starts at the Forest Technology Center at Sylvamo, where studies and research are developed adding productivity and quality of raw materials.

The cultivation of Eucalyptus tree forests is benefited with actions such as genetic improvement and cloning of the best matrices to be planted. The seedlings are planted according to criteria that ensure the best development conditions for trees.

During growing periods, Eucalyptus tree forests are constantly monitored in order to avoid potential damages caused by plagues, diseases or forest fires. All our forests are renewable, always allying the commercial planting to the reconstitution of natural forests. Not forgetting about the preservation of native species and wild fauna in the region. We follow strict environmental standards.

After seven years of cultivation, the Eucalyptus tree is ready to be harvested and used in the paper manufacturing process. New seedlings are also planted and cultivated, guaranteeing a closed, renewable and responsible consumption cycle when using commercial Eucalyptus tree forests.

Logs go through a large barking drum where they collide with one another and abrade to the point barks are removed. The barks that fall off through denting on the drum walls are collected and used as fuel in the boilers. The peeled logs go through a chipper, which reduces them into 1-inch chips (wood chips). In order to extract pulp, chips are taken to the digester, which works like a pressure cooker. The wood is cooked together with chemicals for up to 4 hours until the mixture is reduced to a dark color pulp paste. That process dissolves the lignin, substance that unites the pulp fiber. The pulp is washed to remove chemicals. It goes through a bleaching process that eliminates all impurities, becoming bleached pulp.

Water is added to the pulp in a ratio of 100 portions of water to one portion of fiber. It is pulverized over a sheet canvas. Thus, the paper sheet starts getting shape and grammage, set through adjustments of speed and concentration of the bleached pulp.

With the paper machine running at high speed, Chamex is pressed between felts, and the water is removed by drying through drums called dryers. After drying out, paper receives a coat of starch to enhance its printing characteristics, put to dry again in a new section of dryers. Next, it goes through a pressing and smoothing process aimed at smoothing the surface and control thickness. Paper goes then to the reeler where the sheet becomes a large roll of paper for future production of smaller rolls in rereelers, named reels.

Reels follow pre-established size standards, destined to graphic customers, represented by Chambril paper line. In order to have the cut-size of Chamex, Chamequinho and other brands sold by Sylvamo, reels continue the process going through paper cutters, where they become cut-size paper sheets, adopting format and grammage standards.

Packing machines are responsible for packing 100- or 500-sheet cut-size paper, according to the amount established by Chamex and Chamequinho lines. The packed sheet packs are called reams and grouped into 5-, 10-, 12- or 50-unit boxes. After boxing reams, boxes are sent to shipment.

At shipping, Chamex, Chamequinho and Chambril papers are shipped in trucks responsible for their transportation to distributors all over Brazil. Distributors forward papers to points of sales: stationery stores, bookstores, supermarkets, computing stores, etc. There, you can find the entire Chamex and Chamequinho paper line to be perfectly used in your activities.
