Poor quality napkins turn into residue after being soaked in water, while wood pulp napkins still take shape after being soaked in water. "Falling debris indicates that the quality of the napkins is not up to standard, and it is likely produced through the recycling of waste paper."
According to the quality inspection department's testing, low-quality napkins and tissues contain various fungi, Escherichia coli, tuberculosis, hepatitis viruses, etc., which can easily cause diseases such as enteritis, typhoid fever, dysentery, and hepatitis. In addition to the harmful effects of these bacteria on the human body, producers also add bleach during the production process, which contains carcinogenic chemicals. For example, fluorescent whitening agents contain heavy metal cadmium, which can cause damage to the blood system and impair memory.
Experts suggest that you should not use inferior napkins that have fallen off. When dining out, try to bring your own handkerchief, tissue, or clean your mouth after meals. When purchasing napkins, it is important to choose products from reputable manufacturers and purchase soft, impurity free, and odorless tissues.
