# Sanitary Napkin Raw Materials: Key Components and Their Functions
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products designed to provide comfort and protection during menstruation. The effectiveness of these products depends on the quality and combination of various raw materials. Understanding these components helps consumers make informed choices about the products they use.
## Core Materials in 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: Soft, breathable, and quick-drying
– Perforated plastic film: Provides a dry surface feel
– Cotton-like materials: For extra softness and comfort
This layer must be non-irritating, allow quick fluid passage, and maintain dryness.
### 2. Absorbent Core
The absorbent core is the heart of the sanitary napkin, responsible for fluid retention. It consists of:
– Fluff pulp: Natural wood pulp that absorbs liquid
– Superabsorbent polymers (SAP): Synthetic materials that can absorb many times their weight in liquid
– Combination of both: Most modern pads use a blend for optimal performance

### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Common materials include:
– Polyethylene (PE) film: Waterproof and flexible
– Breathable microporous film: Allows vapor transmission while blocking liquid
– Cloth-like materials: For more comfortable feel against clothing
### 4. Adhesive Components
Several adhesive elements ensure the pad stays in place:
– Pressure-sensitive adhesive: On the underside to attach to underwear
– Wing adhesives: For securing wings around panties
– Release paper: Protects the adhesive before use
## Additional Functional Components
### 1. Fragrance Additives
Some pads include:
– Deodorizing agents: To mask menstrual odor
– Essential oils: For a fresh scent
– Activated charcoal: For odor absorption
Note: Fragrance-free options are available for sensitive skin.
### 2. Side Barriers
Also called “leak guards,” these raised edges:
– Prevent side leakage
– Are typically made of hydrophobic non-woven material
– Provide extra containment for heavy flow
### 3. Wings
Optional features that:
– Wrap around underwear for better security
– Prevent shifting during movement
– Often made of the same material as the top sheet
## Material Safety and Considerations
When choosing sanitary napkins, consider:
– Hypoallergenic materials for sensitive skin
– Chlorine-free bleaching processes
– Absence of harmful chemicals like dioxins
– Biodegradable or eco-friendly options
## Conclusion
Understanding the raw materials in sanitary napkins helps consumers select products that offer the right balance of comfort, protection, and safety. Manufacturers continue to innovate with new materials and designs to meet diverse needs while addressing environmental concerns. Whether prioritizing absorbency, softness, or eco-friendliness, knowing these components empowers women to make the best choices for their menstrual health.
