Sanitary Pad Raw Material Composition and Properties
Keyword: sanitary pad raw material
Sanitary pads are essential hygiene products used by millions of women worldwide. Understanding the raw materials used in their production is crucial for both manufacturers and consumers. The composition of sanitary pads directly affects their comfort, absorbency, and safety.
Core Absorbent Materials
The primary absorbent layer in sanitary pads typically consists of:
- Wood pulp fluff: The traditional absorbent material, providing good liquid retention
- Superabsorbent polymers (SAP): Modern pads use SAP granules that can absorb many times their weight in liquid
- Cotton blends: Often used in premium products for better skin comfort
Top Sheet Materials
The top layer that comes in contact with the skin is usually made from:
- Non-woven polypropylene: Provides a dry surface feel and quick liquid penetration
- Perforated plastic films: Used in some basic pad designs
- Organic cotton: Found in premium and eco-friendly options
Back Sheet Components
The waterproof backing prevents leakage and is typically composed of:
- Polyethylene film: The most common waterproof barrier
- Breathable microporous films: Used in higher-end products for better air circulation
- Biodegradable materials: Emerging options for eco-conscious products
Adhesive and Other Components
Additional materials include:
- Pressure-sensitive adhesives: For securing the pad to underwear
- Release papers: Protect the adhesive before use
- Fragrance additives: Used in some scented varieties (though potentially irritating for sensitive skin)
Key Properties of Sanitary Pad Materials
Quality sanitary pad materials must exhibit:
- High absorbency and retention capacity
- Softness and comfort against the skin
- Breathability to reduce moisture buildup
- Hypoallergenic properties for sensitive skin
- Durability during use
Manufacturers continue to innovate with new materials that improve performance while addressing environmental concerns. The choice of raw materials significantly impacts the final product’s effectiveness, comfort, and ecological footprint.
