Productive Process
All paper that is produced by Imporpel is 100% recycled.
The recycling of paper begins with this scrap paper, our raw material, undergoing a process called disintegration, which consists in disaggregating the used boxes in the water with intense agitation, giving rise to a pulp that will go through several equipments for the removal of impurities.
In a laboratory analysis, a sample of the pulp is evaluated to determine if it is compatible with the required properties of the fibers.
Removal of the water from the pulp is done by gravity, by vacuum, by mechanical compaction and finally by heating the paper sheet. This heating is done through cylinders heated by the circulation of water vapor.
Cardboard boxes that are already used, collected, pressed and packed are called scrap paper.
Then the paste goes to the refiners, which will leave the fibers more uniform.
The formation of the paper is then initiated through an equipment called an headbox that will spread the pulp by a continuous jet on a screen that is supported by a flat table, where water withdrawal begins.
After drying in the paper machine, the paper goes to the rewinder, which will make the paper cutouts of the size requested by the customers.
After passing through the quality control, they are ready to be delivered.
