# 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 the raw materials used in their production. Understanding the composition and properties of sanitary pad materials helps consumers make informed choices and manufacturers improve product quality.
## Core Components of Sanitary Pads
### Top Sheet (Cover Layer)
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 film
– Silk or cotton blends for premium products
Key properties:
– Soft and gentle on skin
– Quick-drying surface
– Breathable to prevent irritation
– Hypoallergenic materials
### Absorbent Core
This is the most critical component that determines the pad’s absorption capacity. Common materials include:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Cotton fibers
– Airlaid paper
Absorption characteristics:
– High liquid retention capacity
– Rapid absorption rate
– Effective distribution of fluid
– Minimal rewet (keeping surface dry)

### Back Sheet (Barrier Layer)
The back sheet prevents leakage and is usually composed of:
– Polyethylene film
– Breathable microporous film
– Non-woven fabric composites
Important features:
– Liquid-proof barrier
– Flexible and comfortable
– Some allow moisture vapor transmission
– Noise-free materials for discretion
### Adhesive Components
These include:
– Pressure-sensitive adhesive for attachment to underwear
– Release paper backing
– Wing adhesives (if applicable)
Adhesive requirements:
– Strong enough to stay in place
– Easy to remove without residue
– Skin-friendly formulation
– Temperature-resistant
## Additional Features and Materials
### Fragrance Components (Optional)
Some pads include:
– Natural essential oils
– Synthetic fragrances
– Deodorizing agents
Considerations:
– Potential for skin irritation
– Masking odors effectively
– Long-lasting fragrance release
### Wing Materials (If Applicable)
Wing components often use:
– Non-woven fabric
– Elastic materials
– Special adhesives
Wing functionality:
– Secure fit
– Prevent side leakage
– Comfortable during movement
## Material Safety and Environmental Considerations
### Safety Standards
All materials must comply with:
– FDA regulations
– EU REACH compliance
– ISO standards
– Dermatologically tested
### Eco-Friendly Alternatives
Growing trends include:
– Organic cotton topsheets
– Biodegradable backsheets
– Plant-based SAP
– Chlorine-free fluff pulp
Environmental benefits:
– Reduced plastic content
– Faster decomposition
– Sustainable sourcing
## Conclusion
The composition of sanitary pad raw materials directly impacts product performance, comfort, and safety. Manufacturers continue to innovate with new materials that offer better absorption, increased comfort, and reduced environmental impact. Understanding these components helps consumers choose products that best meet their needs while being mindful of health and ecological considerations.
