# Sanitary Pad Raw Materials: Composition and Key Components
## Understanding the Basics of Sanitary Pad Construction
Sanitary pads are essential feminine hygiene products designed to absorb menstrual flow. The effectiveness and comfort of these products largely depend on the quality and composition of their raw materials. Modern sanitary pads are sophisticated products that combine various materials to achieve optimal absorption, comfort, and protection.
## Core Components of Sanitary Pads
### 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 polypropylene or polyethylene
– Perforated plastic films
– Cotton or other natural fibers for premium products
This layer needs to be soft, breathable, and quick-drying to maintain comfort during use.
### 2. Absorbent Core
The absorbent core is the heart of the sanitary pad, responsible for fluid retention. It usually consists of:
– Fluff pulp (wood cellulose)
– Superabsorbent polymers (SAP)
– Combination of both materials
The ratio of these materials determines the pad’s absorption capacity and thickness.
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Common materials include:
– Polyethylene film
– Breathable microporous films
– Biodegradable materials in eco-friendly options
### 4. Adhesive Layer
This component keeps the pad securely in place:
– Pressure-sensitive adhesives for attachment to underwear
– Non-slip materials like silicone dots on the wings
## Additional Features in Modern Sanitary Pads
### Wings
Many pads include side wings that fold over the edges of underwear for extra protection. These are typically made from the same material as the top sheet but may have additional adhesive strips.
### Fragrance Components
Some pads incorporate:
– Microencapsulated fragrance beads
– Natural essential oils
– Odor-neutralizing agents
### Barrier Leg Cuffs
Premium products may feature:
– Raised elastic edges
– 3D protection zones
– Leak-proof barriers
## Emerging Trends in Sanitary Pad Materials
The industry is seeing a shift toward:
– Organic cotton topsheets
– Biodegradable backsheets
– Chlorine-free fluff pulp
– Plant-based superabsorbent materials
– Antibacterial treatments using natural ingredients like aloe vera or tea tree oil
## Quality and Safety Considerations
Manufacturers must ensure:
– Hypoallergenic materials
– Dermatologist-tested components
– Absence of harmful chemicals like dioxins
