Legislation, migration

Legislation limits not only the amount, but also the nature of what may be allowed to migrate. For example, the main plasticisers allowed for food contact polymers are listed in Table 10.4.

As a consequence of EU Directive 78/142/EEC, which introduced a limitation of vinyl chloride monomer both as residual amount in final articles (QM lmg/kg) intended to come into contact with foodstuffs and in migration to food (SML not detectable LOD 0.01 mg/kg), the corresponding necessary analytical methods were developed between several European expert laboratories and laid down as agreed methods in EU Directives 80/766/EEC and 81/432/EEC, respectively. This piece of the EU harmonization process was too time- and work-consuming to continue in this way. The vinyl chloride Directives therefore remain a unique feature in EU food packaging legislation since this was found to be impractical for generalization.
