6 points help you better understand the process of Sanitary Napkin Machine?

As a universally needed product especially for girls and women, in our daily life, Sanitary napkin is necessary. But how much do you know about the sanitary napkin machine? Basically the production process of sanitary napkin equipment involves the following steps:

Pulverization

In this process, the wood pulp is pulverized using a pulverizing machine at high speeds to make it voluminous and absorbent. Currently most sanitary napkin production processes use the major absorbent layer as the Wood Pulp. This step is one where manual processes have not been used. But automation can be carried out in a centralized place where pulverized wood pulp can be safely transported to smaller production units if access to power is a problem in remote rural areas.

Core Formation

Once the wood pulp is pulverized, layers of absorbent material are arranged and the absorbent core is made. To increase the comfort levels of the napkin, layers of cotton is also added along with the wood pulp. The wood pulp is packed into the Core forming die using manual presses or a core forming machine. Layers of pre‐cut cotton layer, gel pad are arranged above that. An impermeable layer is placed at the bottom. In some cases the impermeable bottom layer is secured using Super Glue to the above layers. The layers of Gel pad, impermeable layer are to be cut in the standard sizes.

Covering Layer

Once the absorbent layers are formed they need to be covered to secure the layers properly. This is done by inserting the layers into the covering layer which is either stitched or sealed by a Napkin finishing machine where the core layer is sealed using a heat sealing machine. Additional to the outer layer, one unit uses an extra layer to secure the core layer. This is being done to ensure that the wood pulp and other absorbent layers do not move to the sides of the pad during transporting, handling, sorting etc.

Accessories Formation

For belt less and Wings model sanitary napkins, once the napkin is formed with the outer layer, to mark the absorbent layer for identification, super glue is applied on the bottom side (with the non-permeable layer at the bottom) and a release sheet is affixed as a marker. For belt less napkins, when the release sheet is removed, the napkin can be used with as a panty‐liner.

Sterilizing

The finished napkins are sterilized for removal of any harmful bacteria or infectious germs. There are two methods of sterilizing: autoclaving and UV Irradiation

Packaging

Normal packaging is either 8 napkins or 10 napkins. If the napkins are to be sold per piece, a small packing is done. Polyethylene is used for the packing of finished napkins in order to prevent the napkins from reabsorbing moisture.
