Quality assurance is the foundation of a reliable feminine hygiene supply chain. As Tayue, a professional sanitary napkin factory, we specialize in producing cotton sanitary pads, sanitary pads for sensitive skin, and sanitary pads for heavy flow needs. To ensure every product meets global expectations for safety, absorption, and comfort, we implement a strict 10-step QC system aligned with ISO and ASTM standards across the entire production cycle.
1. Incoming Material Inspection & Supplier Qualification
All raw materials such as SAP, nonwoven fabric, and fluff pulp are inspected under ISO 9001 and ISO 9073 standards.
Pass criteria: SAP absorption ≥ 50× its weight, pulp whiteness ≥ 90, moisture content ≤ 10%, defect rate ≤ 1%.
2. Online Thickness & Weight Monitoring
During production, real-time sensors monitor product structure consistency.
Standards: ISO 9073-2
Pass criteria: Thickness tolerance ±0.1 mm, weight deviation ≤ ±3%.
3. Absorption Rate Sampling Inspection
Samples are tested for liquid absorption speed and capacity.
Standards: ASTM D570 / ISO 11948
Pass criteria: Absorption within 3 seconds, retention capacity ≥ 10× product weight.
4. Backflow Volume Testing
This ensures dryness after pressure simulation.
Standards: ISO 9073-6
Pass criteria: Rewet value ≤ 0.1 g under 7 kPa pressure.
5. Microbial Testing
Hygiene safety is strictly controlled.
Standards: ISO 11737-1
Pass criteria: Total aerobic count < 100 CFU/g, no E. coli or Staphylococcus aureus detected.
6. Overall Appearance Inspection
Visual and structural checks ensure product consistency.
Standards: AQL 1.5 inspection level
Pass criteria: No visible stains, deformation rate ≤ 0.5%, adhesive misalignment ≤ 1 mm.
7. Packaging Seal Integrity Testing
Ensures safe transportation and storage.
Standards: ISO 11607
Pass criteria: Seal strength ≥ 1.5 N/15mm, leakage rate ≤ 0.5%.
8. Finished Product Aging Test
Simulates long-term storage conditions.
Standards: ASTM F1980
Pass criteria: 40°C/75% RH for 7 days, performance degradation ≤ 5%.
9. Pre-Shipment Sampling Inspection
Final batch verification before delivery from the sanitary pad factory.
Standards: AQL 2.5
Pass criteria: Major defect rate ≤ 1.0%, critical defects = 0.
10. Third-Party Recheck
Independent labs verify compliance before export.
Standards: SGS / Intertek protocols
Pass criteria: Full compliance with ISO 13485 hygiene product requirements.
