Statement of composition

At Siegwerk, we provide information on potentially migrating substances present in our inks via a Statement of Composition (SoC), in order to allow our customers the evaluation of migration from their individual printed food packaging structure. These SoC’s are in line with EuPIA (European Printing Ink Association) recommendations and are based on current regulatory frameworks.

For the European market, the regulatory base for the SoC is the framework regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food. Possible migrants are listed with their specific migration limits (SML) according to the Plastics Regulation (EU) No 10/2011, and the Swiss Ordinance SR 817.023.21. For the Non-European market, we have developed several specific regional SoC templates, if legislation on food contact materials is in place and applicable as for example in Mercosur (GMC Framework Resolution N° 03/92). Furthermore, for an overview on applicable food contact legislation in all our relevant regional markets, a global template is available on request.

Commitment to transparency

Our Statement of Composition lists those substances with the potential to migrate along with the migration limits as specified in applicable legislation e.g. Regulation (EU) No 10/2011 or the Swiss Ordinance SR 817.023.21. Furthermore, it shows the amount of the migrant within the solid ink film. This allows our customer to perform a worst case calculation taking into account own printing parameters as well as the real packaging structure. Additionally, the Statement of Composition offers results of worst case calculations for relevant migrants, based on specific worst case conditions (EU-Cube, 3 g/m2 ink deposit, 100 % surface coverage, 100 % migration).

Worldwide, we are committed to disclose all information to our customers that is necessary for the identification and quantification of intentionally added (IAS) as well as non-intentionally added (NIAS) substances, which are relevant for migration.
