Functional Barrier Qualification for Mineral Oil Hydrocarbon Migration in Board
Functional barrier qualification requires gas chromatography verification of saturated and aromatic hydrocarbon migration below detection limits on creased board.
European Regulation 1935 2004
Legislative Scope
Chemical migration limits dictate the safety of food contact materials within the European Union. European regulation 1935 2004 establishes the general requirements for all substances intended to come into contact with foodstuffs to ensure human health protection. It mandates that manufacturers produce materials under appropriate quality assurance systems so that no component transfers into food at levels harmful to health or causing unacceptable changes in composition.
This framework applies to every material type, whether plastic, paper, metal, or adhesive, acting as the primary legal foundation for all secondary measures that govern specific substrates.
Compliance Verification
Documentation providing evidence of material safety remains mandatory for every link in the supply chain. Converters and printers demonstrate conformity by supplying a declaration of compliance that identifies the chemical components and their migration potential when exposed to food simulants. Paper mills support this process by testing pulp and additive migration against specific limits defined in related directives for fibrous substrates.
Third party laboratory analysis validates that ink components or coating binders do not exceed established migration thresholds during normal use conditions. Such certification provides proof that the final package maintains structural integrity without contaminating the contents.
Operational Constraints
Analytical limits restrict the application of this standard to materials showing detectable substance transfer under defined testing protocols. Testing procedures assume worst case scenarios for temperature and duration to account for varied food packaging shelf life. Regulations necessitate that firms implement internal tracking to ensure that a finished product can be traced back to its raw material source if a safety issue appears.
Manufacturers bear the liability for ensuring that the migration levels remain beneath the prescribed threshold until the moment the package reaches the consumer. Compliance with these protocols defines the legal ability to market materials for food contact across the internal market.
