# Sanitary Pads Raw Material: Key Components and Their Functions

Sanitary pads are essential personal care products designed to provide comfort and hygiene during menstruation. Understanding the raw materials used in their production is crucial for ensuring quality and safety. This article explores the key components of sanitary pads and their respective functions.

## 1. Top Sheet

The top sheet is the layer that comes into direct contact with the skin. It is typically made from a non-woven fabric or a perforated film. The primary function of the top sheet is to allow quick absorption of menstrual fluid while keeping the surface dry and comfortable.

## 2. Absorbent Core

The absorbent core is the most critical component of a sanitary pad. It is usually made from a blend of wood pulp and superabsorbent polymers (SAP). The wood pulp provides bulk and helps in the even distribution of the fluid, while the SAP is responsible for locking in the moisture, preventing leakage.

## 3. Back Sheet

The back sheet is the outermost layer of the sanitary pad, often made from a polyethylene film. Its main function is to prevent any leakage from the pad, ensuring that the menstrual fluid is contained within the absorbent core. The back sheet also provides a barrier against external contaminants.

## 4. Adhesive

Adhesive is applied to the back sheet to keep the sanitary pad securely in place within the underwear. This adhesive is usually pressure-sensitive and designed to be strong enough to hold the pad in position while being easy to remove without leaving residue.

## 5. Release Paper

The release paper is a protective layer that covers the adhesive before the pad is used. It is typically made from silicone-coated paper or film. The release paper is peeled off to expose the adhesive when the pad is ready to be used.

## 6. Fragrance and Additives

Some sanitary pads include fragrances or additives to provide a pleasant scent or additional comfort. However, these components are optional and can sometimes cause irritation for individuals with sensitive skin. It is essential to choose products that suit your personal preferences and skin type.

## Conclusion

Understanding the raw materials used in sanitary pads helps consumers make informed choices about the products they use. Each component plays a vital role in ensuring the pad’s effectiveness, comfort, and safety. By knowing what goes into the making of sanitary pads, users can better appreciate the technology and care involved in their production.
