# Diaper Material Composition Guide
## Understanding Diaper Materials
Modern diapers are complex products designed for maximum comfort and absorbency. Knowing the materials used in their construction can help parents make informed choices for their babies.
## Core Diaper Components
### 1. Outer Layer (Backsheet)
The waterproof outer layer is typically made from:
- Polyethylene film
- Polypropylene non-woven fabric
- Breathable microporous films (in premium diapers)
### 2. Absorbent Core
This critical component usually contains:
- Fluff pulp (wood cellulose)
- Superabsorbent polymers (SAP)
- Sometimes cotton or bamboo fibers
### 3. Top Sheet (Inner Layer)
The layer against baby’s skin often consists of:
- Polypropylene non-woven fabric
- Polyester materials
- Sometimes with aloe or vitamin E coatings
## Additional Components
Elastic Components
Stretchable parts typically use:
- Polyurethane
- Spandex
- Elastic threads
Adhesive Systems
Diapers use various adhesives including:
- Hot melt adhesives
- Pressure-sensitive adhesives
- Reusable tape systems
## Eco-Friendly Alternatives
For environmentally conscious parents:
- Bamboo fiber diapers
- Organic cotton diapers
- Plant-based SAP alternatives
- Biodegradable backsheet materials
## Safety Considerations

Some parents prefer diapers without:
- Chlorine-bleached materials
- Fragrances
