Verifying Mass Balance Ledgers for Chemical Recycled Polymers
Verifying chemical recycled polymer mass balance ledgers requires physical boundary mass-loss accounting, yield deductions, and batch-level credit transfer documentation.
Food Contact EU 10 2011
Meaning
European Union legislation establishes a positive list of authorized substances that may be used in the manufacture of plastic materials intended to come into contact with food. The regulation known as food contact eu 10 2011 sets out specific migration limits for monomers, additives, and polymer production aids to prevent the transfer of harmful chemicals to food. This comprehensive standard applies to both virgin and recycled plastics.
Regulatory Framework
Plastic converters must issue a formal declaration of compliance showing that their finished articles meet these safety rules. Under food contact eu 10 2011, manufacturers must verify that the migration of overall substances does not exceed ten milligrams per square decimeter of food contact surface. This keeps packaging inert.
Compliance Mechanism
Testing labs use food simulants like ethanol, acetic acid, and vegetable oil to model different food types. The food contact eu 10 2011 guidelines prescribe specific temperature and time exposures to replicate actual storage conditions. This ensures that the migration testing is representative of real world use.
Testing Requirement
Substances not on the approved list are prohibited unless they fall under specific derogations for functional barriers. This restricts the use of unapproved recycled inputs or additives in food contact articles.
