Swiss Ordinance 817.023.21 for Packaging Inks

The Swiss Federal Department of Home Affairs (DFI) adopted in March 2008 an amendment to the Ordinance of 23 November 2005 on Materials and Objects in Contact with Food (SR 817.023.21). It entered into force on 4 January 2010 and lays down the obligation for packaging inks to be manufactured only with the authorized substances. Permitted substances are defined as those listed in Annex 2 Lists I and II and in Annex 10, December 2020.

The lists in the Ordinance simply states that the substances may be used in the manufacture of printing inks. To ensure safety in accordance with the law, the migration limits for substances must not be exceeded for final packaging. Guides of Good Practice for the manufacture and printing of printing inks should be followed.

Substances listed with status 'B' may be used, provided that the final packaging is in compliance with the requirements of the Ordinance, i.e. the migration of the listed substances cannot be detected using a valid and official analytical method. The migration should not be greater than 0.01 mg / kg (10 ppb).

INX carried out a review of the raw materials used in the products below to determine their status with respect to the Swiss Ordinance and found that the products below meet the Swiss Ordinance Annex 10.

Accordingly, it does not automatically mean that the product or substance is toxicologically suitable to be used for printing inks for all types of food packaging.

Flexibility & Adhesion

These inks are formulated to achieve excellent adhesion to a wide variety of substrates and compatibility with wide range of banner stocks, vinyl and paper.

Temperature Exposure & Jetting

Inks were optimized to jet in equipment operating at 25°C. Changes in ambient temperature and controlled temperature settings affect the viscosity of the ink and therefore the accuracy of drop formation and dot placement. Prolonged exposure to temperatures above 55°C should be avoided as long term exposure to high temperatures can induce pigment agglomeration.

Ink Storage and Shelf Life

These inks should be stored between 15° - 30°C (59° - 86°F). When stored properly inks have a 15 month shelf life.

Recommended Flush
