They are classified as hygiene products under the management category of disinfection products, and the hygiene permits for their manufacturers are approved by the provincial health administrative departments.
[0003] Napkins come in dry and wet varieties, but dry napkins are more commonly used and have replaced handkerchiefs or towels. They come in various names, such as handkerchief paper, facial tissue, napkin, hand towel, scented tissue, and paper towel. They are all made from crepe paper and come in different packaging, including bags, boxes, tubes, and rolls. Generally, these products are suitable for cleaning the face, hands, and other items, but not for cleaning or sterilizing tableware. Furthermore, the quality of these products varies greatly; it's best to choose those with a fine, dense, resilient texture that doesn't wrinkle. A napkin production line typically includes a paper tray module, a folding module, a packaging module, and a paper output module.
