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.
EN 71–3:2019+A1:2021 Toy Safety Standard
This product is formulated from ingredients whose chemistry excludes the nineteen elements regulated by EN 71 Part 3:2019+A1:2021 (Appendix B).
Like all synthetic and naturally occurring chemical substances, raw materials, as received from our suppliers, may conceivably contain trace amounts of these metals. It is recommended to prove if the thresholds for metals are respected.
INX Digital is dedicated to the development of UV inks and proudly commits to formulating future products without the use of TPO (Triphenylphosphine Oxide), underscoring our commitment to environmental sustainability and meeting evolving industry standards.
Introduction, what is TPO?
All energy curable inks, including UVCurable, use a component called photo-initiator to trigger the reaction of curing, transforming a liquid into a solid film; such reaction is the polymerization. There are many photo-initiators, but the ink-jet inks manufacturing industry uses TPO for the majority of the times. INX Digital is no exception. TPO typically refers to “Triphenylphosphine Oxide,” which is a photoinitiator. Photoinitiators like TPO play a crucial role in the curing process of the ink when exposed to UV light, initiating the reaction that transforms the liquid ink into a solid coating. However, it comes with some toxicological concern.
Health concerns related to TPO
TPO went through an analytical consideration by European authorities for quite some time during the past few years, and a decision was made recently for a reclassification, due to increased toxicity concerns. The European Chemicals Agency’s new legislation recommends classifying TPO as Reprotoxic 1B, reflecting potential harm to fertility and the unborn child. Already classified in the USA and some Asian countries, the process is happening in Europe, where TPO now requires additional safety concern exposures (on Safety Data Sheets), like mentioning that TPO is enlisted in the SVHC list (Substance of Very High Concern) from REACH.
EuPIA and Exclusion Policy
INX Europe Ltd is an associate member of EuPIA, and a voluntary signee of the declaration of honoring compliance with the Exclusion Policy. The Exclusion Policy applies to all types of printing inks, applied in all types of printing processes, including inkjet, and for all end use applications, and citing from the EuPIA website, “has been an important code protecting the health and safety of workers in the ink and printing industries, as well as the end users of printed materials. In 1996 the European sector group of the printing ink industry took over existing national stewardship initiatives to create the Exclusion List for Printing Inks and Related Products. It applied stricter rules to the manufacture and marketing of inks than the existing legal regulations would have required. In taking this responsibility, the European ink industry took a proactive lead for the world.INX Digital, as a division of INX Europe Ltd, will be fully compliant with this policy.
TPO in EuPIA Exclusion Policy List
With this reclassification taking place, TPO has been enlisted in the EuPIA Exclusion Policy List of restricted materials, and all members who have voluntarily signed for being compliant, need to remove this component from their formulations.INX Digital is now extensively working to remove TPO from all formulations, including ink-jet inks. All UVCurable inks will undergo a reformulation for being safer and healthier for workers and end users.

These inks should be stored between 15° - 30°C (59° - 86°F). When stored properly inks have a 12 month shelf life.

HKM inks are formulated to achieve optimum adhesion on commonly used flexible and rigid display graphics media. Specific media such as PE and Acrylic can be problematic so the customer should test these materials before conversion. Many times the use of BondAid adhesion promoters can fix adhesion issues.

Inks can be used in jetting equipment with temperatures up to 60°C. Prolonged exposure to temperatures above 55°C however, should be avoided as long term exposure to high temperatures can induce premature polymerization.
