Sanitary pad material

A high-performance sanitary pad requires a combination of specialized layers. The Top Sheet should be made of Non-woven fabric (Spunbond or Hot Air-through) or Perforated Film for rapid infiltration. The Absorbent Core typically consists of Fluff Pulp mixed with Super Absorbent Polymer (SAP) to ensure high retention capacity. The Back Sheet must be a Breathable PE Film to prevent leakage while allowing air circulation. Additionally, Release Paper and Hot Melt Adhesives (Construction and Positioning) are critical for structural integrity and user convenience.

SAP is the most critical component for fluid management. You must evaluate it based on Absorbency Under Load (AUL), Free Swell Capacity, and Liquid Permeability. High-quality SAP should have a fast absorption rate (less than 30 seconds) and a high retention rate to prevent re-wetting. It is recommended to request technical data sheets (TDS) and perform a centrifuge retention capacity (CRC) test before bulk procurement.

Since these materials come into contact with sensitive skin, they must meet strict safety standards. Ensure suppliers provide ISO 9001 for quality management and ISO 14001 for environmental standards. Materials should be Oeko-Tex Standard 100 certified to guarantee they are free from harmful substances. For entry into the US market, FDA registration is often required, while the EU market necessitates CE marking and compliance with REACH regulations regarding chemical safety.

There is a significant shift toward eco-friendly options. B2B buyers should look for 100% Organic Cotton top sheets, Bamboo fiber non-wovens, and PLA (Polylactic Acid) biodegradable back sheets. Bio-based SAP and TFC (Totally Chlorine-Free) fluff pulp are also in high demand. Sourcing these materials can provide a competitive advantage in premium and environmentally conscious markets.

Sanitary pad materials, especially fluff pulp and non-wovens, are highly sensitive to humidity. You should insist on vacuum packaging or heavy-duty PE wrapping for all rolls. Ensure the container is inspected for holes and use industrial-grade desiccants (silica gel) inside the container. Choosing FOB terms allows you more control over the carrier and container quality compared to CIF.

Focus on GSM (Grams per Square Meter) tolerance, which should not exceed ±5%. Negotiate volume-based pricing tiers, as raw material costs fluctuate with petroleum and wood pulp prices. Request a fixed price agreement for 6-12 months to stabilize your production costs. Additionally, verify if the supplier can provide customized roll widths to minimize waste on your specific production machinery.

For secure transactions, use Trade Assurance services or Letters of Credit (L/C) for large volumes. To ensure consistency, require a Pre-Shipment Inspection (PSI) by a third party like SGS or Intertek. Always request production samples from the actual batch being shipped, rather than just 'golden samples' from the showroom, to verify that the tensile strength and hydrophilicity meet your specs.

For professional B2B sourcing, Made-in-China.com is a premier platform to connect with audited manufacturers of non-wovens, SAP, and PE films. Look for 'Audited Suppliers' on the platform to ensure the factory has undergone rigorous on-site verification of their production capacity and quality control systems.
