# 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 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 plastic film
– Cotton or bamboo fibers for premium products
Key properties: Softness, breathability, quick-dry capability
### 2. Absorbent Core
This is the most crucial component that determines the pad’s absorption capacity. Common materials include:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Combination of both
The core may also include:
– Airlaid paper
– Tissue layers for better distribution
### 3. Back Sheet (Barrier Layer)
The back sheet prevents leakage and is usually made from:
– Polyethylene film
– Breathable microporous film
– Biodegradable materials in eco-friendly options
Important characteristics: Leak-proof, flexible, comfortable
### 4. Adhesive Components
These include:
– Pressure-sensitive adhesive for attachment to underwear
– Release paper backing
– Wing adhesives (for winged pads)
## Additional Materials and Features
### Fragrance and Deodorizers
Some pads incorporate:
– Natural plant extracts
– Activated charcoal
– Chemical deodorants (controversial)
### Special Additives
Premium products may include:
– Aloe vera for soothing effect
– Vitamin E for skin care
– Antibacterial agents

## Material Properties and Performance
### Absorption Capacity
Determined by:
– SAP content (can absorb 30-60 times its weight)
– Fluff pulp quality
– Core structure design
### Comfort Factors
– Breathability (especially important for back sheet)
– Flexibility
– Surface dryness
– Skin-friendliness
### Safety Considerations
– Hypoallergenic materials
– Non-toxic components
– Dermatologically tested
## Environmental Impact of Materials
Growing concerns have led to:
– Development of biodegradable materials
– Organic cotton options
– Reduced plastic content
– Compostable packaging
## Future Material Trends
Emerging innovations include:
– Plant-based superabsorbents
– Nanotechnology for better performance
– Smart materials with moisture indicators
– Fully compostable pad designs
Understanding these material components helps consumers choose products that match their needs for comfort, protection, and environmental responsibility. Manufacturers continue to research and develop new materials to improve performance while reducing ecological impact.
