Swiss Ordinance SR 817.023.21

Statutory Law

Legal requirements for the composition of printing inks and packaging materials in Switzerland are defined by a comprehensive piece of national legislation. The swiss ordinance sr 817.023.21 is famous for its detailed positive lists of substances that are permitted for use in the manufacture of food contact materials. It covers everything from pigments and resins to plasticizers and solvents.

This law is often used as a benchmark by global companies because it is more detailed than most other national regulations.

Migration Limit

Limits on the amount of a substance that can transfer into food are strictly enforced under this code. The swiss ordinance sr 817.023.21 specifies that any substance not on the approved list must not be detectable in the food at a level above ten parts per billion. This ensures that unknown or untested chemicals do not pose a risk to the consumer.

Positive List

Manufacturers must verify that every ingredient in their ink or coating is included in the annexes of the ordinance. If a new chemical is developed, it must undergo a full safety assessment before it can be added to the swiss ordinance sr 817.023.21 list. This system provides a high level of transparency and safety for the entire packaging supply chain, from the chemical supplier to the final consumer.
