Ink for food packaging

Monday, November 10, 2014

imageDomino has produced a white paper for companies in the food supply chain entitled ‘Inks for food packaging’, to clarify the regulations and guidelines that govern use of inks for food packaging as well as coding and marking, either printed directly onto food or packaging, using continuous ink jet (CIJ) techniques. 

While the inks used for coding and marking in food production – which comprises Use By or Sell By dates or batch numbers – constitutes a fraction of all printed inks used in the food packaging process, the rules surrounding its use are complex in their application in different countries. 

Domino’s white paper outlines the key regulations (EU and non-EU) and related issues, such as migration of inks from packaging into food and migration in the offset printing process.  It also explores the effectiveness of different substrates in providing adequate barrier protection against the risk of migration.

An active member of EuPIA (the European Printing Ink Association), Domino observes relevant regulations and guidelines that govern the use of printing inks and has set its own stringent criteria in the development of its own specialist inks and fluids for food packaging.  This criteria includes a declaration regarding the suitability of these inks for food packaging applications.

Andrew Gunton, Product Manager – Fluids at Domino says, “Packaging specifiers, food producers and converters need to ensure that the combination of packaging and inks or varnishes used in the printing process do not enter foodstuffs.  Similarly, with inks used for coding and marking, there is a risk of chemicals being transferred to food, especially when the inks are printed onto packaging where there may be a risk of migration.  By being fully conversant with the relevant regulations outlined in our white paper parties in the food supply chain can take appropriate action to mitigate these risks.”
