Comprehensive guide to raw materials used in modern sanitary napkins - structure, composition, and selection criteria
Sanitary napkins are made of 3 core raw material components + auxiliary materials:
Auxiliary sanitary napkin raw materials: Hot melt adhesive, release paper, easy tape, leak guards, functional chips.
Sanitary napkin raw materials are the core of product performance, directly affecting absorption, comfort, safety and environmental protection. According to IMARC Group research, the global sanitary napkin market was valued at USD 28.0 Billion in 2024 and is expected to reach USD 38.0 Billion by 2033 (CAGR 3.46% from 2025 to 2033).
"Most women lack clear knowledge about sanitary napkin raw materials, even though they use sanitary pads daily."
Understanding sanitary napkin raw materials helps consumers choose safe products and manufacturers optimize production processes. This guide covers all key raw materials, structures and selection standards.
Qualified sanitary napkin raw materials must pass strict international safety certifications to ensure skin-friendly and non-toxic performance:
Sanitary napkins adopt a 3-layer structure, all made of professional sanitary napkin raw materials:
Direct skin contact layer, made of soft raw materials for quick liquid conduction.
Core absorption layer, the most critical sanitary napkin raw materials for liquid locking.
Bottom protective layer, made of waterproof & breathable raw materials.
Cotton Material: Natural, non-irritating, ideal for sensitive skin
Bamboo Fiber: Natural antibacterial, breathable, eco-friendly high-end raw material
Perforated PE Film: Quick dry, suitable for high-absorption products view details
Absorbent core raw materials determine the absorption performance of sanitary napkins, mainly including 4 key materials:
Wood pulp fiber, soft, fast liquid absorption, basic raw material of absorbent core
High-molecular absorbent material, locks liquid dozens of times its weight SAP raw material
Waterproof + breathable, reduces stuffiness, used in high-end sanitary pads
Soft, breathable, matched with film for balanced performance
Other auxiliary raw materials: leak guards, antibacterial chips, packaging materials, fragrances (for specific products).
| Raw Material Type | Advantages | Disadvantages | Application Scene |
|---|---|---|---|
| Non-woven Fabric | Low cost, good permeability | Natural feeling is average | Daily & mid-end products |
| Natural Cotton | Skin-friendly, soft | High cost, slow absorption | Sensitive skin & high-end |
| SAP | Super absorption, anti-backflow | High cost | Night & heavy flow |
| Breathable PE Film | Waterproof + breathable | Higher price | High-end sanitary pads |
With the rise of environmental protection, biodegradable raw materials have become the development trend of the sanitary napkin industry:
These eco-friendly raw materials can be naturally degraded after use, reducing white pollution and meeting the needs of green consumers.
