Quality Control

Fortune Cat™:Zero Compromise. Full Traceability.

We operate a multi-stage quality management system aligned with ISO 13485 (medical devices), ISO 9001, and GMP guidelines. Every batch of sanitary pads, diapers, or sheet masks – especially chitosan-based and fully biodegradable products – undergoes rigorous testing before shipment.


1. Incoming Raw Material Control (IQC)

Material CategoryTests PerformedAcceptance Criteria
Nonwoven fabrics (top sheet, back sheet)Gram weight, tensile strength, liquid strike-through±5% of spec; no tears
Chitosan fiber/fabricDegree of deacetylation (DD), molecular weight, antibacterial activity (ASTM E2149)DD ≥90%; >99% reduction vs E. coli & S. aureus
Biodegradable film (PLA/PBAT)Thickness, biodegradability certificateEN 13432 or ASTM D6400
SAP (superabsorbent polymer)Absorbency under load (AUL), retention capacityAUL ≥20 g/g; retention ≥25 g/g
Fluff pulpWhiteness, moisture content, foreign matter≤8% moisture; chlorine-free
Mask fabric & serumpH, microbial count, chitosan content (for chitosan masks)pH 4.5–6.5; total plate count <100 CFU/g

All chitosan raw materials are accompanied by third-party test reports for heavy metals (Pb, Hg, As, Cd) and residual protein (for hypoallergenic claims).


2. In-Process Quality Control (IPQC)

We perform real-time checks at critical control points:

Sanitary Pads & Diapers Line

StageCheck
Web laminationAdhesion strength, layer alignment
Core formingSAP/fluff distribution uniformity (±2g)
EmbossingPattern clarity, no over-pressure
Folding & packingCount accuracy, seal integrity (peel test)

Sheet Mask Line

StageCheck
Fabric cuttingDimension tolerance (±1.5mm)
Serum fillingFill weight (±2%), no leakage
Pouch sealingSeal strength (hot tack test)

Every 30 minutes – operators record dimensional, weight, and visual data.
Every 2 hours – line supervisor performs functional testing (strike-through, rewet, mask serum release).


3. Finished Product Testing (OQC)

Before release, finished products are sampled per AQL Level II (ANSI/ASQ Z1.4) :

For Sanitary Pads & Diapers

TestMethodStandard
Absorbency (synthetic menstrual fluid)ISO 11948-1 / GB/T 8939≥30mL for regular; ≥60mL for overnight
Rewet (surface dryness)ISO 11948-1 (modified)≤1.0g for chitosan pads
LeakageDynamic fluid penetrationZero leakage under 2kPa pressure
pH of surfaceEN 13726-14.5–7.5
Biodegradability (for eco line)EN 13432 / ASTM D6400≥90% disintegration in 12 weeks
Chitosan antibacterial activity (if claimed)ASTM E2149 or JIS L1902≥90% reduction

For Sheet Masks

TestMethodStandard
Microbial limitUSP <61>/<62>No pathogens; TPC <100 CFU/g
Chitosan content (for chitosan mask)Colloidal titration or HPLC≥0.5% (w/w) of fabric weight
Serum pH and viscosityUSP <791> + BrookfieldAs per formula spec
Skin irritationHET-CAM or patch test (human repeat)Non-irritant

4. Biodegradability & Compostability Verification

For fully biodegradable pads and diapers:

  • Disintegration test – ISO 16929 / EN 13432 (pilot-scale composting)
  • Ecotoxicity test – Plant growth ≥90% of control
  • Certificate – Issued by DIN CERTCO, TÜV OK Biodegradable, or BPI (upon project)

We provide batch-specific biodegradation certificates for EU/export markets.


5. Microbiological & Sterility Control

Although our products are non-sterile, we maintain strict limits:

ProductTotal Aerobic CountYeast & MoldS. aureusPseudomonasCandida
Sanitary pads / diapers≤100 CFU/g≤20 CFU/gAbsentAbsentAbsent
Sheet masks≤100 CFU/g≤10 CFU/gAbsentAbsentAbsent

Products can be gamma or EO sterilized upon request (medical-grade diapers or wound-care masks).


6. Traceability & Batch Records

Every finished good carries a unique batch number printed on the master carton. Our traceability system links:

  • Raw material lot number
  • Production line and date
  • IPQC operator ID
  • OQC test report
  • Shipping destination

Batch records are retained for 5 years minimum.


7. Stability & Shelf-Life Testing

We conduct real-time and accelerated stability studies per ISO 11607 / ISTA:

ConditionDurationTests Performed
40°C ± 2°C / 75% RH3 months (accelerated)Absorbency, pH, microbial, seal strength
25°C ± 2°C / 60% RH12–24 months (real-time)Full functional + biodegradability (for eco line)

Result: Minimum shelf life of 2 years for pads and diapers, 3 years for unopened sheet masks.


8. Third-Party Audits & Certifications

We welcome customer or third party audits. Current certifications include:

CertificationScope
ISO 13485:2016Design & manufacture of absorbent hygiene products (Class I medical device in some markets)
ISO 9001:2015Quality management system
OEKO-TEX® STANDARD 100Product class I or II (upon project)
FDA (US)Device listing for sanitary pads / adult diapers
CE (EU)MDR compliance for absorbent products (if applicable)
BPI / DIN CERTCOBiodegradability for eco line (project-based)

Additional certifications (BCI cotton, FSC, vegan, cruelty-free, halal) can be arranged per order.


9. Customer Rejection & Non-Conformance Handling

Any non-conforming batch triggers our CAPA system:

  1. Quarantine – blocked from shipment
  2. Root cause analysis – within 48 hours
  3. Corrective action – process or material adjustment
  4. Preventive action – updated FMEA and operator training

Rejection rate (customer claims) maintained at <0.2% over last 24 months.


10. Quality Reports We Provide Upon Shipment

With every commercial order, you receive:

  • Certificate of Analysis (CoA) – batch-specific test results
  • Raw material certificate (from our suppliers, including chitosan DD and biodegradability)
  • AQL sampling report
  • Seal integrity & leakage test summary
  • Biodegradability certificate (if applicable)

Third-party lab reports (SGS, TÜV, Intertek) available at additional cost.
