# Sanitary Napkin Raw Materials Overview

## Introduction to Sanitary Napkin Components

Sanitary napkins, also known as menstrual pads, are essential feminine hygiene products used by millions of women worldwide. These products are carefully designed to provide comfort, absorption, and protection during menstruation. Understanding the raw materials used in their production helps consumers make informed choices about the products they use.

## Core Materials in Sanitary Napkins

### 1. Top Sheet (Cover Stock)

The top sheet is the layer that comes in direct contact with the skin. It’s typically made from:

– Non-woven polypropylene
– Perforated plastic film
– Cotton or other natural fibers (in organic options)

This layer must be soft, breathable, and allow for quick liquid transfer to the absorbent core.

### 2. Absorbent Core

The absorbent core is the heart of the sanitary napkin, responsible for retaining menstrual flow. Common materials include:

– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Combination of fluff pulp and SAP

– Bamboo fiber (in eco-friendly options)

### 3. Back Sheet

The back sheet prevents leakage and keeps moisture from reaching clothing. Materials include:

– Polyethylene film
– Breathable microporous film
– Biodegradable materials (in some eco-friendly products)

### 4. Adhesive Components

Sanitary napkins include several adhesive elements:

– Pressure-sensitive adhesive for panty attachment
– Hot melt adhesive for layer bonding
– Release paper for protecting the adhesive before use

## Additional Components

### Wings and Side Barriers

Many modern sanitary napkins feature:

– Side barriers to prevent leakage
– Wings that fold under underwear for better protection
– Elastic components for better fit

### Fragrance and Additives

Some products may include:

– Deodorizing agents
– Aloe vera or other soothing additives
– Antimicrobial treatments

## Environmental Considerations

With growing environmental awareness, manufacturers are exploring:

– Biodegradable materials
– Organic cotton options
– Chlorine-free bleaching processes
– Reduced plastic content

## Conclusion

Understanding the raw materials in sanitary napkins helps consumers choose products that align with their comfort needs, health considerations, and environmental values. As technology advances, we continue to see innovations in materials that improve performance while reducing environmental impact.
