The effectiveness and comfort of these products depend heavily on the quality and composition of their raw materials. Understanding these components helps consumers make informed choices about the products they use during menstruation.

## Core Materials in Sanitary Napkins

### 1. Absorbent Core

The absorbent core is the most critical component of a sanitary napkin, typically made from:

– Wood pulp (fluff pulp)
– Superabsorbent polymers (SAP)
– Combination of both materials

This layer is responsible for quickly absorbing and retaining menstrual fluid to prevent leakage and maintain dryness.

### 2. Top Sheet (Cover Stock)

The top sheet comes in direct contact with the skin and is designed for:

– Quick fluid absorption
– Dry surface feel
– Skin comfort

Common materials include:

– Nonwoven fabrics (polypropylene or polyethylene)
– Perforated plastic films
– Cotton-like materials for premium products

### 3. Back Sheet

The back sheet serves as a barrier to prevent leakage and is usually made from:

– Polyethylene film
– Breathable microporous films
– Biodegradable materials in eco-friendly options

### 4. Adhesive Components

Sanitary napkins include several adhesive elements:

– Pressure-sensitive adhesive strips to secure the pad to underwear
– Hot melt adhesives to bond different layers together
– Release paper to protect the adhesive before use

## Additional Features and Materials

– Individual wrappers (plastic or paper)
– Outer packaging (boxes or plastic bags)
– Biodegradable options becoming more common

## Quality and Safety Considerations

Manufacturers must ensure:

– Hypoallergenic materials
– Absence of harmful chemicals
