Migration testing is often required to demonstrate that a material complies with the migration limits set out in food contact regulations. Migration testing rules vary depending on material and region.
The EU Regulation 10/2011 sets out two types of migration limits for plastic materials, covering overall migration (OML) and specific migration (SML).
Overall Migration Studies
The overall migration limit is the cumulative figure of substances which can migrate out of the food contact material. The analysis provides a holistic overview of the substances found in the food sample or food simulant.
Specific Migration Studies
These studies focus on known individual substances, based on toxicological data. Migration testing identifies whether these substances can be found in the food sample or food simulant.
Printing Ink Migration
Our experts can also undertake migration tests on printing inks, and advise on their toxicological impact. We have significant expertise in compliance testing against both the GMP Regulation (EC) No 2023/2006 and the Framework Regulation (EC) No 1935/2004.
We can help:
- Identify whether your substance requires migration testing
- Advise on the most appropriate exposure techniques, test conditions and food simulants for your particular need
- Undertake a standard migration test to assess your material
- Develop a bespoke test method for substances which fall outside of the listed standard test methods.
