This layer needs to be soft, breathable, and quick-drying to maintain comfort.
### 2. Absorbent Core
The absorbent core is the heart of the sanitary napkin, responsible for fluid retention. Common materials include:
– Wood pulp (fluff pulp)

– Combination of both materials
The ratio of these materials determines the absorption capacity of the pad.
### 3. Back Sheet
The back sheet prevents leakage and keeps moisture from reaching clothing. Materials used include:
– Polyethylene film
– Breathable microporous films
– Biodegradable materials in eco-friendly options
