# Sanitary Napkin Raw Materials: Essential Components for Hygiene Products
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products used by millions of women worldwide. The effectiveness and comfort of these products depend on the quality and combination of various raw materials. Understanding these components helps consumers make informed choices and manufacturers develop better products.
## Core Materials in Sanitary Napkins
### 1. Top Sheet (Cover Stock)
The top layer that comes in direct contact with the skin is typically made from:
– Non-woven fabric (polypropylene or polyethylene)
– Perforated plastic film
– Cotton or cotton-blend materials
This layer needs to be soft, breathable, and quick-drying to maintain comfort and prevent irritation.
### 2. Absorbent Core
The heart of the sanitary napkin consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Sometimes blended with cotton or rayon
This layer is responsible for absorbing and retaining menstrual flow effectively.
### 3. Back Sheet
The waterproof bottom layer is usually made from:
– Polyethylene film
– Breathable microporous film
– Biodegradable materials in eco-friendly options
This prevents leakage while allowing some breathability in premium products.
## Additional Components
### 1. Adhesive Strips
Most sanitary napkins include:
– Pressure-sensitive adhesive for panty attachment
– Release paper to protect the adhesive before use
### 2. Wings (in winged designs)

– Non-woven materials
– Sometimes with additional adhesive
### 3. Fragrance and Additives
Some products may contain:
– Deodorizing agents
– Aloe vera or other soothing additives
– Antimicrobial treatments
## Emerging Trends in Materials
