Rigorous Clinical Testing
Verified by Independent Accredited Laboratories
Professional delivery packaging requires zero margin for thermal failure. SvartxLab bags undergo strict evaluations for heavy metals, aromatic amines, and total migration across extreme temperature thresholds — all performed by CNAS-accredited independent laboratories under ISO/IEC 17025:2017 standards.

Thermal Retention Performance
Our ProThermo™ multi-layer insulation system maintains food-safe temperatures across extended delivery windows. Each bag is tested under simulated worst-case delivery conditions per EU 10/2011 Annex V, verifying sustained thermal retention from 40°C to 100°C across multiple exposure durations.
Migration Test Results
All migration parameters tested fall well below regulatory thresholds. Each bar shows the actual measured result as a proportion of the maximum allowable limit — the smaller the bar, the safer the material.
Chemical Safety Analysis
Every material layer is independently tested for hazardous substances via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) at parts-per-billion sensitivity. Zero tolerance for carcinogenic compounds.
What Our Clients Say
“Hot food arrives hot, cold food arrives cold. The aluminum film lining means nothing leaks through and the outside stays dry even in rain.”
“The ease of unfolding the bag and the fact that it's waterproof on the outside — a game changer during rainy season. Our team is absolutely thrilled with the bags.”
“Same-day or next-day delivery was the deciding factor. Customer support is always available whenever we have a question.”
Testing Methodology
Our certification process follows a strict 4-phase protocol executed by independent accredited laboratories, ensuring every production batch meets international food-contact safety standards.
Material Sampling
Random specimens are extracted from each production batch under controlled conditions. Samples are sealed and tracked with unique lot identifiers to ensure chain-of-custody integrity.
Chemical Spectrometry
Specimens undergo Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to detect heavy metals at parts-per-billion sensitivity, alongside gas chromatography for aromatic amine screening.
Migration Testing
Total migration simulants (acetic acid, ethanol, olive oil) are applied at regulatory temperatures (40°C, 70°C, 100°C) for defined durations per EU 10/2011 Annex V protocols.
Compliance Verification
Results are cross-referenced against EU 1935/2004, GB 4806, and ISO 17025 thresholds. Only batches with zero parameter exceedances receive the CNAS-verified clearance certificate.
Standards Glossary
Verifiable definitions of the applicable certification standards
- CNAS
- China National Accreditation Service for Conformity Assessment — China's laboratory accreditation body, the functional equivalent of UKAS in the UK or A2LA in the US. Its accreditation is globally recognized through ILAC-MRA.
- ILAC-MRA
- International Laboratory Accreditation Cooperation Mutual Recognition Arrangement — A multilateral agreement ensuring that test results from CNAS-accredited labs are accepted in 100+ countries, including all EU member states.
- GB 4806.13-2023
- China's national food-contact safety standard — the functional equivalent of EU 1935/2004. It regulates total migration, heavy metals, aromatic amines, and sensory properties. Sub-standard 4806.13 specifically covers bags and wraps for food contact.
- EU 1935/2004
- The EU framework regulation on materials and articles intended to come into contact with food. It sets general safety requirements and authorizes specific measures for different material types (plastics, metals, textiles, etc.).
FAQ
Who certifies the materials?
All SvartxLab materials are subjected to rigorous testing via CNAS and ILAC-MRA accredited independent laboratories, specifically Fangyuan Test (方圆检测). We do not self-certify — every result is verifiable through the accreditation body.
What temperatures are the bags tested at?
Bags are tested simulating worst-case scenarios for delivery environments, reaching core retention limits from 40°C to 100°C across multiple exposure durations per EU 10/2011 Annex V. Real-world thermal performance is validated at 60–70°C sustained for 4+ hours.
Are the bags compliant with EU Regulation 1935/2004?
Yes. EU 1935/2004 governs all materials intended for food contact within the European Union. Our bags are tested for total migration, specific migration of heavy metals, and sensory properties — all within the regulation's strict thresholds.
What does the GB 4806 standard cover?
GB 4806 is China's national food-contact safety standard series. Our certification covers GB 4806.7 (plastics) and GB 4806.8 (composites), testing for decolorization, potassium permanganate consumption, and heavy metal migration at elevated temperatures.
Are SvartxLab bags BPA-free?
Absolutely. Our multi-layer insulation system uses no Bisphenol A (BPA) in any composite layer. This is independently verified during the aromatic amine and specific migration testing phase of our CNAS certification process.
