Compliance Limit
European plastic food contact regulations establish the maximum allowable amount of a given chemical substance that can migrate from packaging into food. The specific migration limit eu 10 2011 is a legally binding threshold designed to protect consumer health by restricting the transfer of monomers, additives or processing aids. This standard applies directly to all plastic layers used in multi-material laminates and paperboard barriers.
Risk Assessment
Chemical substances like plasticizers, antioxidants and unreacted monomers can pose health risks if they are ingested in large quantities. The specific migration limit eu 10 2011 is based on toxicological evaluations, which determine the acceptable daily intake for each listed substance. When a packaging supplier selects materials for food contact, they must verify that the levels of these potential migrants remain well below the established regulatory thresholds.
This verification is crucial for fatty or acidic foods, which are highly effective at extracting chemical components from polymer films.
Testing Protocol
Converters and food packers must demonstrate compliance by performing migration tests with food simulants under defined time and temperature conditions. These tests use substances like ethanol or vegetable oil to mimic the extraction behavior of different foods over the product shelf life. If the analytical results show that any migrant exceeds the specific migration limit eu 10 2011, the packaging material is declared non-compliant and cannot be used in the European market.
Manufacturers frequently run predictive mathematical models of diffusion to screen new packaging designs before committing to expensive laboratory testing.
