Sanitary Pad Raw Material Composition and Properties

# Sanitary Pad Raw Material Composition and Properties

## Introduction to Sanitary Pad Materials

Sanitary pads are essential feminine hygiene products designed to absorb menstrual flow. The quality and comfort of these products largely depend on their raw material composition. Understanding the materials used in sanitary pad production helps consumers make informed choices and manufacturers improve product quality.

## Core Components of Sanitary Pads

### 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 fabric (polypropylene or polyethylene)
– Perforated plastic film
– Cotton or bamboo fiber blends

Properties: Soft, breathable, quick-drying, and hypoallergenic.

### 2. Absorbent Core

This is the most crucial layer responsible for fluid absorption. Common materials include:

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

Properties: High absorption capacity, good retention, and minimal rewet.

### 3. Back Sheet

The waterproof layer that prevents leakage. Materials include:

– Polyethylene film
– Breathable microporous film
– Biodegradable alternatives like PLA (polylactic acid)

Properties: Liquid-proof, flexible, and comfortable.

### 4. Adhesive Components

– Pressure-sensitive adhesive for pad attachment
– Hot melt adhesive for layer bonding

Properties: Strong enough to stay in place but gentle on clothing.

## Additional Features and Materials

### 1. Wing Materials

Most wing pads use:

– Non-woven fabric
– Elastic materials for better fit

### 2. Fragrance Components

Some pads include:

– Natural essential oils
– Synthetic fragrances (though these may cause irritation)

### 3. Barrier Leg Cuffs

Found in premium pads, made from:

– Special non-woven materials
– Elastic components
