# Sanitary Napkin Raw Materials: Essential Components for Hygiene Products
## Introduction to Sanitary Napkin Components
Sanitary napkins are essential feminine hygiene products used by millions of women worldwide. The effectiveness and comfort of these products depend heavily on the quality and combination of their raw materials. Understanding these components helps consumers make informed choices about the products they use during menstruation.
## Core Materials in Sanitary Napkins
### 1. Absorbent Core
The absorbent core is the most critical component of a sanitary napkin, typically made from:
– Wood pulp (fluff pulp)
– Superabsorbent polymers (SAP)
– Combination of both materials
This layer is responsible for quickly absorbing and retaining menstrual fluid, keeping the surface dry and comfortable.
### 2. Top Sheet (Cover Stock)
The top sheet is the layer that comes in direct contact with the skin. Common materials include:
– Non-woven fabric (polypropylene or polyethylene)
– Perforated film
– Cotton-like materials for premium products
This layer needs to be soft, breathable, and allow quick liquid penetration while keeping the surface dry.
### 3. Back Sheet
The back sheet prevents leakage and maintains the pad’s shape. Materials used include:
– Polyethylene film
– Breathable microporous film
– Biodegradable materials in eco-friendly options
This layer must be waterproof yet comfortable against clothing.
## Additional Components
### 4. Adhesive System
Sanitary napkins feature two types of adhesives:
– Body adhesive to keep the pad in place on underwear
– Packaging adhesive to secure individual wrappers
### 5. Release Paper
This protective layer covers the adhesive before use, typically made from:
– Silicon-coated paper
– Plastic film
### 6. Side Barriers (Wings)
Many modern pads include side barriers or wings made from:
– Non-woven materials
– Elastic components for better fit
## Specialized Materials in Premium Products
High-end sanitary napkins may incorporate:
– Aloe vera or vitamin E coatings for skin care
– Charcoal layers for odor control
– Antibacterial treatments
– Organic cotton covers
– Biodegradable or plant-based materials
## Safety Considerations
Manufacturers must ensure all materials:
– Are dermatologically tested
– Free from harmful chemicals
– Comply with international safety standards
– Cause minimal environmental impact
