There is no connection between the two. Many people think that the whiter the paper is, the cleaner it is. This is a mistake that consumers often fall into. The cost of paper bleaching is very high, but it has nothing to do with the hygiene index. Toilet paper as long as health indicators can be achieved, there is no need to emphasize white, emphasize finish. Napkins, facial tissues and handkerchiefs are sometimes emphasized, but it is also because of consumers’ personal aesthetic, preferences and other factors. As long as you are willing to bear the cost of bleaching, you can care whether it is in white or not, and whether there are exquisite patterns. It all depends on the individual.
