European Food Contact Polymer Migration Limit Determination
European food contact compliance requires validating overall and specific migration limits using designated simulants, geometric ratios, and traceable dossiers.
Commission Regulation EU 10 2011
Meaning
Harmonized legislative frameworks establish chemical safety criteria and compliance rules for plastic packaging materials intended to contact foodstuffs across the European single market. Within European packaging supply chains, Commission Regulation (EU) No 10/2011 defines positive lists of authorized monomers and additives alongside polymer production aids. The regulatory standard specifies overall migration limits alongside substance-specific migration limits for compounds capable of leaching into food.
It governs resin selection, masterbatch formulation, melt processing, and converter manufacturing, applying directly to virgin plastics while deferring recycled content rules to separate safety frameworks.
Migration Standard
Quantitative limits constrain the maximum mass of non-volatile chemical constituents that may pass from a plastic article into food simulants. Compliance under Commission Regulation (EU) No 10/2011 requires testing at specified time and temperature conditions that reflect anticipated food contact exposure. Standard overall migration limits cap total migration at ten milligrams per square decimetre of plastic contact area.
Higher migration values render a plastic packaging component non-compliant for commercial food distribution.
Simulant Testing
Testing regimes select standardized liquid simulants representing aqueous, acidic, alcoholic, and fatty food types. Plastic plaques undergo exposure testing in standardized cells to measure overall and specific substance transport into chosen simulants.
Compliance Limit
Specific migration limits apply to specialized additives like plasticizers and antioxidants. Converters must obtain declarations of compliance from polymer suppliers to verify that raw resin formulations contain only authorized substances within permitted concentration thresholds. Processing temperatures during injection moulding must be managed to prevent thermal degradation of additives into non-listed reaction products.
