When buying paper, you should see clearly what type of paper you are buying. If it is toilet paper, the raw material can be recycled paper. When testing this type of toilet paper, the state allows reasonable addition of some recycled materials and fluorescent agents. Therefore, the requirements for this type of toilet paper are relatively low. A colony index of gram below 600 meets the standard. It’s okay for people to use the toilet for one use.
Napkins are different. Considering that they will touch the face and lips of the human body, the production and testing standards are more stringent. When making napkins, fluorescent agents are not allowed. Moreover, the detection of napkins is more stringent, and the colony index per gram should be less than 200. Compared with toilet paper, napkins are cleaner and require more testing procedures. Napkins can clean the face, softer and safer.
In addition, toilet paper will take into account the convenience of flushing the toilet, and most of them will choose paper that is easier to dissolve in water. Although it is hard to the touch, it is easier to break when wet. The napkin will be more resilient. After being wet with water, it is not easy to break. This can also be used as a way to distinguish the two.
