Other processes such as embossing, cutting, and packaging may also be included in the production process to meet the needs of different consumers. The edge-sealing technology of household paper mainly involves sealing the edges of multiple layers of paper to improve the durability and aesthetics of the tissue. The following are the principles of several common edge-sealing technologies: Heat-sealing technology: Using a heat-sealing machine to heat the edge part of the tissue, so that the fibers of the paper are bonded together at high temperature.
