[0002] Panty liners and mini sanitary napkins are essential sanitary products for women, and their quality is directly related to women's health. The design of mini sanitary napkins makes them more suitable for use when the menstrual flow is light, and their longer length and larger absorption capacity can meet this demand. Panty liners are more suitable for daily use during non-menstrual periods, such as when there is a lot of leucorrhea or odor, because they are small and easy to carry and have a smaller absorption capacity.
