Meaning
Analytical testing standards established under European packaging regulations govern the individual quantitative extraction of authorized monomers, additives, plasticizers and metals from plastics into food simulants. Protocol execution under en 13130 specific migration verifies that targeted chemical substances do not transfer into food contact media above legally binding substance-specific migration limits. The standard encompasses multi-part analytical procedures for regulated substances in food contact plastics, stopping where unlisted non-intentionally added substances require open structural identification rather than targeted quantification.
Analytical Methodology
High-sensitivity chromatography and mass spectrometry quantify minute trace chemical residues extracted from plastic test specimens. Laboratories expose plastic samples to aqueous, alcoholic, acidic or fatty simulants under standardized contact times and temperatures. Following exposure, analysts utilize gas chromatography, high-performance liquid chromatography or inductively coupled plasma mass spectrometry to measure target analytes against calibration standards.
Testing protocols in the en 13130 specific migration series define specific analytical methods for substances such as caprolactam, terephthalic acid, bisphenol compounds, phthalate esters and heavy metal stabilizers. Method limits of quantification must operate well below established legal restrictions.
Processing Interactions
Thermal history during polymer compounding and extrusion blow moulding dictates the degradation and release of migrating chemical species. Excessive melt temperatures promote polymer chain scission, freeing monomers and generating volatile degradation fragments. Slip additives, light stabilizers and primary antioxidants may decompose or partition more rapidly into food matrices if barrel residence times run excessively long.
Uncontrolled regrind addition introduces degraded stabilizer complexes that alter migration dynamics and can exceed specific migration limits. Converters optimize temperature profiles and cooling rates to minimize additive breakdown while achieving full mechanical seam fusion.
Procurement Governance
Purchasing contracts for food-grade polyolefins, masterbatches and functional barrier materials demand verifiable specific migration data. Material compliance declarations must list all substances subject to specific migration limits, accompanied by certified laboratory validation under en 13130 specific migration. Sourcing professionals cross-reference resin supplier substance declarations with the European Union positive list before authorizing resin substitutions.
Independent laboratory testing validates that finished converted containers comply with specific limits before commercial packaging supply agreements take effect.
