What Are Disposable Sanitary Napkins Made Of? A 2026 Buyer's Material Guide

Published: 2026-08-08 | Reading time: 12 minutes

Disposable sanitary napkins are multi-layer hygiene products typically constructed from a top sheet, an absorbent core, a backsheet, and an adhesive system. For procurement teams, the material specification of each layer determines absorbency, skin compatibility, biodegradability, and cost. This guide explains what disposable sanitary napkins are made of, how eco-friendly bio-based versions differ from standard constructions, and how to evaluate a sanitary napkin manufacturer's material capabilities in 2026.

Why Material Composition Matters to Buyers

The global sanitary pads market was valued at approximately USD 20.4 billion to USD 25.73 billion in 2024, with growth projected at a CAGR of 4% to 5.6% through 2034. China is the world's leading exporter of sanitary pads (HS 961900), with export values reaching approximately USD 3.3 billion to USD 3.59 billion in 2024. As competition increases, buyers are differentiating their product lines on material transparency and sustainability rather than price alone.

Regulatory and consumer pressure is also shifting material choices. Certified compostable sanitary napkins must adhere to European standard EN 13432 or North American ASTM D6400, requiring 90% biodegradation within 6 months in industrial conditions. In the United States, sanitary napkin products are covered by FDA Establishment Registration under 21 CFR Part 807. These compliance requirements are directly tied to which raw materials are used in the top sheet, core, and backsheet.

For importers, distributors, and private-label brands, understanding the material stack is also a risk-management tool: a verifiable material specification prevents substitution, quality disputes, and failed certification audits.

Anatomy of a Disposable Sanitary Napkin: Standard vs. Bio-Based

A disposable sanitary napkin is a layered composite. Each layer has a distinct function: fluid intake, distribution, retention, and leak protection. The two material families a buyer will encounter in 2026 are standard petroleum-based constructions and bio-based/plant-derived constructions.

Standard Series Material Construction

The FC-Standard Series by Ecolivia is a disposable sanitary napkin made of non-woven fabric, Super Absorbent Polymer (SAP), and breathable bio-film, available in 240mm, 285mm, 330mm, and 410mm lengths. This composition represents the mainstream construction used in wholesale, B2B distribution, and supermarket channels.

• Non-woven fabric top sheet: Provides a dry-touch surface and allows fluid to pass quickly into the core.
• SAP (Super Absorbent Polymer) core: Locks fluid inside the pad and prevents rewetting under pressure.
• Breathable bio-film backsheet: A biodegradable film backing that reduces moisture build-up while preventing leakage.
• High-speed absorption core: Designed for mass-market absorbency at a competitive price point.

Bio-Based Series Material Construction

The Ecolivia-Bio Series is a disposable sanitary napkin made of organic cotton, bamboo fiber, and advanced bio-based core, with a length range of 155mm to 450mm and customizable absorbency options (high, super, and night). This construction is designed for retail, FMCG, and sustainable brands targeting premium eco-conscious consumers.

• Organic cotton top layer: A plant-derived contact layer associated with hypoallergenic and chemical-free positioning.
• Bamboo fiber layer: A rapidly renewable plant fiber used in the distribution or comfort layer.
• Advanced bio-based absorbent core: Replaces a portion of petroleum-derived SAP with bio-derived materials while maintaining liquid retention.

The organic cotton sanitary napkin segment reached a market value of approximately USD 3.95 billion in 2025, with growth driven by consumer preference for hypoallergenic and chemical-free products. This validates the commercial relevance of the organic cotton material route for private-label programs.

Material-Level Breakdown: Step by Step

Here is how a bio-based disposable sanitary napkin is built, layer by layer, using the Ecolivia-Bio Series as the reference construction.

1. Organic cotton or bamboo fiber top sheet: The first layer in contact with the skin. It is designed to be soft, breathable, and free of optical brighteners, targeting fluorescent-free compliance.
2. Acquisition and distribution layer: A non-woven layer that quickly transfers fluid from the top sheet into the core, preventing pooling on the skin surface.
3. Advanced bio-based absorbent core: The retention layer. In the bio-based design, a combination of plant-derived fibers and modified absorbent materials provides the holding capacity. Absorbency is customizable: high, super, and night.
4. Breathable bio-film backsheet: The bottom protective layer that blocks leaks while permitting air and moisture vapor exchange.
5. Adhesive and release paper: The garment-attachment system. The release paper protects the adhesive strip before use.

For a standard mass-market construction, the FC-Standard Series follows the same layer logic but uses a conventional SAP core and non-woven fabric top sheet, allowing high-speed production and lower unit cost.

Material Compliance Checklist

• GOTS certification for organic cotton fiber claims.
• FSC certification for wood-pulp or paper-based packaging.
• EN 13432 or ASTM D6400 for compostability claims.
• FDA Establishment Registration (21 CFR Part 807) for U.S. market entry.
• Fluorescent-free verification for the top sheet.
