Tissue paper is truly rooted in the daily life of modern society due to the wide variety of products that make different applications possible. For this type of industry, it is a huge challenge to produce the best products to retain the final consumer. Simulations using the finite element method (FEM) allow the optimization, in a virtual environment, of operating conditions of embossing process (pressure, rubber hardness and finishing geometry of the engraved steel plates pattern) to obtain the best compromise between the different properties and a final product of excellent quality, thus avoiding an expensive trial-error approach. Through
the FEM analysis, it was also possible to optimize the perforation geometry (cut distance, blank distance, geometry of perforation line), to obtain the best efficiency and guarantee that service is detached by the perforation line.
