EU Packaging Regulation Enters Force Requiring PFAS and Metal Conformity Files
Buyers must secure Declarations of Conformity and PFAS-free test results for all packaging entering the European Union.
Chemical Testing
Compositional Verification
Analytical laboratory procedures executed to identify, quantify, and validate the chemical constituents and physical properties of industrial substances form the foundation of material qualification. Termed across commercial compliance frameworks as chemical testing, these empirical protocols establish whether incoming feedstocks, intermediate mixtures, and finished polymers conform to contractual purity specifications and regulatory safety mandates. The boundary encompasses destructive elemental analysis, spectroscopic verification, chromatographic separation, and thermal profiling across accredited testing environments.
It ceases to apply once a material passes verification and is integrated into irreversible conversion processes or released into consumer trade channels.
Analytical Frameworks
Laboratory evaluation applies specific instrument methods to quantify trace contamination, active ingredient concentration, and residual volatile compounds within production batches. Gas chromatography coupled with mass spectrometry separates volatile organic mixtures to detect minute impurities that could destabilize downstream reactions. Inductively coupled plasma mass spectrometry measures trace heavy metals down to parts-per-billion thresholds, validating compliance with global environmental directives.
High-performance liquid chromatography profiles non-volatile compounds and polymer additives, while Fourier-transform infrared spectroscopy confirms raw molecular identity against standard spectral libraries. Karl Fischer titration determines residual water content in moisture-sensitive raw materials, preventing catalytic poisoning or hydrolytic degradation during processing.
Execution Protocols
Standardized test procedures governed by global bodies such as ASTM International and ISO define exact sample preparation routines, calibration standards, and measurement tolerances to ensure inter-laboratory reproducibility. Testing protocols mandate certified calibration curves, blank sample runs, and duplicate matrix spikes to verify analytical accuracy before generating legal certificates of analysis. Non-conforming test results trigger secondary referee testing procedures specified in international sales agreements to resolve quality disputes between buyers and sellers.
Industrial facilities rely on these analytical results to adjust batch formulation ratios, confirm environmental effluent compliance, and validate raw material acceptance. The resulting analytical documentation accompanies shipments across international borders to prove structural conformity with customer technical data sheets.
