[0002] At present, common disposable sanitary products include sanitary napkins, paper diapers, paper towels and wet wipes, etc. These disposable sanitary products are widely used, and therefore many improvements have been made to the sanitary products and their packaging. The packaging of disposable sanitary products after production is roughly divided into bagging and boxing. Among them, bagging includes independent packaging and large packaging after independent packaging. For example, multiple products are packaged in small packages to form an independent small package, thereby ensuring that the products are not contaminated or dampened and can be sold and used individually. Then, multiple small packaged sanitary products are packaged in a large package to form a large package of sanitary products that can be sold in the form of a large package. The boxing after bagging facilitates subsequent transportation.
