In-house quality control compliant with ISO 9001
Certified quality, batch by batch.
- Active certificate
- Lot-by-lot traceability
- CoA on every batch
In practice
What it means for our clients.
Four operational guarantees the client gets in every supply.
Lot-by-lot traceability
Each batch is uniquely identified, from raw material to finished product. Full history available on request.
- Unique batch ID
- Document history
- FIFO inventory
In-house quality control
MFI, density, colorimetry and mechanical-property tests run on every production batch by our laboratory.
- MFI · ISO 1133
- Density · ISO 1183
- Tensile · ISO 527
- Color · CIE L*a*b*
Technical documentation
Every shipment is accompanied by a Certificate of Analysis (CoA) to guarantee compliance with the agreed specification.
What it contains:
• Batch test results (MFI, density, color, mechanics)
• Unique batch ID and production date
• Compliance with agreed technical specifications
• Quality manager signature- CoA
- With every shipment
- Test results
- Quality signature
Standardized processes
Standard Operating Procedures (SOP) ISO 9001 certified to ensure maximum stability and repeatability of every single batch.
Key flow stages:
• Intake: raw material control and FIFO lot traceability
• Process: automatic gravimetric dosing and compounding
• Lab: lot-by-lot sampling and in-house testing
• Release: dedicated packaging and tracked shipping- ISO 9001
- Controlled flow
- FIFO traceability
- Periodic audits

ISO 9001 — Quality Management System
ISO 9001 certification is the operational foundation of every production: from raw-material intake to batch release, every step is tracked and documented. It is the minimum standard that the major chemical and petrochemical groups demand of their industrial partners — and the standard Green Plast guarantees, batch after batch.
