Sanitary napkin raw material

Sourcing high-quality raw materials is critical for the performance of the final product. Key components include: Super Absorbent Polymer (SAP), which should have a high absorbency rate (g/g) and excellent retention capacity; Fluff Pulp, preferably untreated or semi-treated kraft pulp for superior wicking; Non-woven Top-sheets, where you must choose between Hydrophilic Spunbond or Hot Air-through for softness and dryness; and PE Back-sheet films, which must be breathable yet 100% leak-proof. Ensure all materials meet ISO 9001 standards for manufacturing consistency.

Since these materials are for personal hygiene, compliance is non-negotiable. You must verify that the materials are hypoallergenic and skin-friendly. Request MSDS (Material Safety Data Sheets) and certifications such as FDA registration, CE marking, or OEKO-TEX Standard 100. For eco-friendly lines, look for biodegradability certifications like TUV OK Compost. Always ensure the supplier complies with REACH regulations regarding chemical substances to avoid skin irritation issues.

Before bulk procurement, test samples for Strike-through time (how fast liquid passes through the top layer) and Rewet values (how dry the surface remains). For the ADL (Acquisition Distribution Layer), evaluate its ability to spread liquid evenly to prevent leakage. For adhesive components, test the peel strength of the positioning glue and construction glue to ensure they remain secure without leaving residue on fabric or causing delamination during use.

To maximize ROI, consider consolidated shipping; many suppliers on Made-in-China.com offer 'one-stop-shop' solutions where you can source SAP, pulp, and films from a single region to reduce logistics costs. Negotiate volume-based pricing, as a 15-20% discount is common for full container loads (FCL). Additionally, monitor the global price of petroleum and wood pulp, as these commodities directly impact the cost of non-wovens and fluff pulp.

The biggest risks are moisture damage during transit and batch-to-batch inconsistency. To mitigate these, insist on vacuum-sealed or moisture-proof pallet packaging. Use third-party inspection services (like SGS or Intertek) to conduct Pre-Shipment Inspections (PSI) to verify that the GSM (grams per square meter) and absorbency levels match the approved samples.

Always use secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow-based trade terms provided by reputable platforms like Made-in-China.com. When negotiating, don't just focus on the unit price; discuss lead time guarantees and defective product compensation clauses. A professional supplier should offer a replacement policy for any material found to be sub-standard upon arrival.

Raw materials like fluff pulp are bulky, so sea freight is the only economically viable option. Ensure your supplier provides a detailed Packing List and CO (Certificate of Origin) to benefit from potential Free Trade Agreement (FTA) tariff reductions. Be aware of anti-dumping duties that some countries may apply to specific non-woven fabrics or chemical components.
