# Sanitary Napkin Raw Materials: Essential Components for Feminine Hygiene Products
## Introduction to Sanitary Napkin Materials
Sanitary napkins are essential feminine hygiene products used by millions of women worldwide. The quality and comfort of these products largely depend on the raw materials used in their production. Understanding the components of sanitary napkins helps consumers make informed choices about the products they use during menstruation.
## Core Components of 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 fabric (polypropylene or polyethylene)
– Perforated plastic film
– Cotton or other natural fibers for premium products
This layer needs to be soft, breathable, and quick-drying to prevent skin irritation.
### 2. Absorbent Core
The absorbent core is the most crucial part of a sanitary napkin. It usually consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Combination of both materials
The SAP can absorb many times its weight in liquid, making modern sanitary napkins much thinner and more effective than older versions.
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Common materials include:
– Polyethylene film
– Breathable microporous film
– Biodegradable materials in eco-friendly options
### 4. Adhesive Layer
The adhesive keeps the pad in place in the underwear. It’s typically:
– Pressure-sensitive adhesive
– Hypoallergenic formulations
– Strips rather than full coverage for easier removal
## Additional Features and Materials
### Wings
Many sanitary napkins feature wings that fold over the sides of underwear. These are usually made from:
– Non-woven fabric
– Plastic film
– Sometimes with additional adhesive
### Fragrance and Additives

– Plant-based adhesives
## Quality and Safety Considerations
When selecting sanitary napkin raw materials, manufacturers must consider:
– Dermatological safety
– Absorbency rates
– Breathability
– Hypoallergenic properties
– Environmental impact
The right combination of materials ensures comfort, protection, and peace of mind during menstruation while minimizing environmental footprint.
