Dr Ralph Derra
ISEGA Forschungs- und Untersuchungsgesellschaft mbH
After his chemistry studies, Dr. Derra became head of laboratory of the ISEGA Forschungs- und Untersuchungsgesellschaft mbH, Aschaffenburg. Since 1986, he has been president of this company. As an authorized state registered expert for the analyses of packaging materials and of soil and air, he attends to the field of certification of materials in contact with foodstuffs. Apart from the analysis and evaluation of foodstuffs packages, environmental effects like re-cycling and composting are main focal points of his work.
Within the new German National Accreditation Body DAkkS, he represents the German Chem-ical Society GDCh in the fields of chemistry and protection of consumer health.
Dr. Derra is chairman of the analytical DIN committees on paper as well as on plastics in food contact and, in this function he also represents the German standardization in the correspond-ing European CEN workgroups. Since 2015, he is Chairman of the CEN/TC 172 Pulp, Paper and Board.
Current developments in the assessment and analysis of adhesives for food packaging
In most cases, an adhesive is not considered as a plastic material. Consequently, the Regulation (EU) No. 10/2011 does not apply. The Union List of Authorized Substances is very helpful for the evaluation of constituents, but it is not complete. Standardized test methods for migration testing according to the Regulation (EU) No. 10/2011 aren’t applicable either in many cases.
The functionality of an adhesive as a component of food packaging and also its formulation is frequently not comparable to a plastic material. A food contact status declaration according to the Plastics Regulation is consequently only possible to a limited extent.
The Regulation (EC) No. 1935/2004 had provided for the possibility to issue an individual measure for adhesives in contact with food. However, so far there is no harmonized legislation for adhesives on the European level.
For a conformity statement on the use of adhesive in food packaging, it is therefore necessary to apply analysis and assessment systems which facilitate a risk assessment of the influence on the individual food types.
