INVENTORY LIST – VERSION June 2012 EuPIA European Printing Ink Association a sector of CEPE aisbl INVENTORY LIST – VERSION June 2012 COMPRISING OF PACKAGING INK RAW MATERIALS APPLIED TO THE NON-FOOD CONTACT SURFACE OF FOOD PACKAGING 12/06/2012 EuPIA Inventory List – Notes & Lists 1. Preliminary note The EuPIA Guideline on Printing Inks Applied to the Non-Food Contact Surface of Food Packaging Materials and Articles already includes a scheme for the careful selection of raw materials to be used in the manufacture of food packaging inks. Nevertheless, EuPIA had decided additionally to make publicly available a list of all the substances used in the manufacture of food packaging inks, with the aim of implementing a transparent tool for packaging converters and brand owners. At the same time the list is intended to become a reference for competent authorities. Since then, the Swiss Ordinance on Materials and Articles has been amended with provisions specific to food packaging inks. The core element of the new regulation is a list of permitted substances identifying the only substances to be used in the manufacture of food packaging inks marketed in Switzerland. However, it is the intention of EuPIA to collate and develop its own inventory list, allowing for the most flexible way of providing update information such that the latest status of substances/raw materials used in food packaging inks is represented. Printing inks and varnishes for food packaging are intended to be applied to a variety of substrates using different printing techniques, such as: • Rotogravure and flexographic printing on flexible films, Aluminium foil, paper and cardboard • Offset printing on paper, cardboard, rigid plastics and metal • Screen printing on rigid plastics, films, foil and metal • Roller coating on metal • Digital inks printed on paper, cardboard, flexible films and Aluminium foils • Jet inks printed on paper, flexible films, Aluminium foils and rigid plastics Depending on the field of application and their formulation, printing inks and varnishes have different drying mechanisms: • Evaporation through hot air drying for water and solvent based systems • Penetration into substrate structures with or without oxidative polymerisation • Radical or cationic polymerisation induced by UV or EB irradiation. • High temperature drying by solvents evaporation and/or polymerisation using baking ovens. In the light of these diversified application requirements the strong chemical distinctions between ink systems and their constituent parts must be stressed. It should also be noted that the composition of the dried applied ink in almost all cases is not identical to the delivered ‘wet’ form. Furthermore it should also be noted that end-user and/or customer requirements may prevent the use of some of the materials below in certain applications. 2. Constituent parts of the Inventory List The Inventory List comprises of seven raw material groups used in the manufacture of food packaging inks and in addition a list of monomers and other precursors permitted to be used in the manufacture of plastic materials and articles in contact with food. The list of additives permitted to be used in the manufacture of plastic materials and articles in compliance with the legal constraints is included: ° Additives - chemical categories - ingredient substances ° Colorants, (i.e. pigments, dyes) ° Pigment additives ° Polymeric resins - generic groups - monomers/precursors/raw materials ° Solvents ° Enery Curing Monomers ° Photo-initiators ° List of monomers and other precursors permitted to be used in the manufacture of plastic materials and articles in contact with food, including additives permitted to be used in the manufacture of plastic materials and articles in contact with food. 3. Additional remarks 3.1 Polymeric substances are described by their monomers and precursors. 3.2 Polymerisation aids like catalysts and starters are not in the scope of the inventory list. 3.3 Pigment preparations are broken back into their ingredients such as colorants, solvents, additives, dispersing aids and polymeric substances (their monomers). These substances are included in the respective substance groups. 3.4 Additives, which are preparations, are broken back into their ingredients such as e.g.detergents (wetting agents), solvents, waxes, plasticisers, polymeric substances (their monomers). These substances are included in the respective substance group. 3.5 Photo-initiators are included in a separate document " EuPIA Suitability List of Photo-initiators for Low Migration UV Printing Inks and Varnishes" (available at www.eupia.org) 3.6 Substances may be covered by generic names where they have no CAS N° and are covered by a group of substances. 4. Additives Additives are substances used normally in small quantities, which essentially impart specific technical properties to the printing ink, primer or overprint varnish. 4.1 Additive groups EuPIA has defined 19 groups of additives application, as shown below: (1) Acid catalyst (2) Adhesion promoter (3) Amine solubiliser (4) Antifoam agent (5) Antimist (6) Antistatic (7) Biocide (8) Chelating agent (9) Dispersing agent (10) Flow agent (11) Gellant (12) Ink stabiliser (13) Optical brightener (14) Photoinitiator (15) Slip agent (16) Suspension agent (17) Thickener (18) UV stabiliser (19) Wetting agent Additives are presented in two different lists: ● chemical categories of the substances and preparations used ● substances used as additives or ingredients of preparations 4.2 Chemical Categories of Additives 1.
