5 What we do. Inkjet inks UV, LED, solvent, mild, true eco-solvent and oil based inks. Available to the major print heads. Water-based Flexographic & Rotogravure inks For printing in porous substrates such as corrugated board and paper. Solvent-based Flexographic & Rotogravure inks To print on substrates based in nonporous applications. Concentrated colour bases To use with Dispensing Units. Solid dispersions (Chips) High Concentration monopigmentary. Varnishes and additives Excellent range of varnishes and auxiliary products. Products and special inks Special dye-solid based inks for specific applications. Confidential 5

6 What means migration? Migration is the unwanted transfer of components from ink, adhesive, varnish, substrate or the enviroment into the packaged goods. Different types of migration:

7 Migration Issues in the past: 2004: Sensorial problem with advent calender; mineral oil from offset inks 2005: ITX in fruit juice, Baby milk (Nestlé); Photoinitiator from UV inks 2009: Benzophenone in cereals; Photoinitiator from UV inks 2010: Mineral oil from recycled board

9 European legislation does not specifically cover printing inks in their supplied form, there are some legislative instruments which impact on materials and articles intended for indirect contact with food. Regulation (EC) No 1935/2004: materials and articles in contact with food do not transfer their components to food in quantities which could: - endanger human health OF COURSE! - affect the composition of the food - degradation in the organoleptic properties

10 Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food. Overall migration limit (OML) of 60 mg/kg food or 10 mg/dm² of surface area. In addition specific migration limits (SML) or maximum contents in the material are set for individual substances (50 ppb). Regulation (EC) No 2023/2006, sets out rules on Good Manufacturing Practices for the production of food contact articles.

11 Responsibility: The manufacturer of the packaging and the filler are responsible for the properties of the food packaging and its compliance with legal requirements. Packaging Chain Substrate Inks Adhesives Others Printer Converter FOOD Company Brand Owner Packaging Company MARKET Responsibility for final food packaging

12 Aspects to know when talking about ink migration All kind of inks have components susceptible to migration Components with molecular weight 1000Da Ink manufacturers have to develop specific low migration formulas Other elements in the production chain to consider: o adhesives o varnishes o the substrate itself (recycled fibers)

13 Let s focus on differences between inkjet inks referent to migration elements: INKJET INKS BENEFITS CHALLENGES UV - UV curing gets minimum penetration in substrate - Formulated in accordance with various standards and regulations possibility of printing products for the indirect food packaging - Recyclability - Photoinitiators - Monomers (should be specific for low migration) WB - No low molecular weight components - Odourless - Biocides - Wetting additives - VOCs - Ph controller additives (MEA)

14 Let s focus on differences between inkjet inks referent to migration elements: INKJET INKS BENEFITS CHALLENGES HYBRID - No hazardous labeling is required - Low ink film (no pile height ) - Photoinitiators - Biocides - Ph controller additives (MEA)

15 There is another Inkjet inks alternatives to consider? INKJET INKS BENEFITS EB - No potential migration photoinitiators - Solvent free - Not dependent on the ink layer - Excellent scratch and chemical resistance CHALLENGES - Complex technology - High structural costs LATEX - No potential migration photoinitiators - PU resins reticulate by IR (high energy consumption) - Heat from IR affect media stability - Evaporate H2O but also VOC's

16 Innovating at DRUPA 2016 with Power CRB UV inks Chimigraf presented its new UV Low Migration ink specially formulated for printing on paper and corrugated cardboard Kao Chimigraf s CRB FDP UV inks complies with regulations and standards applicable to indirect contact food packaging Inkworldmagazine Alabrent

17 CRB FDP UV Inkjet inks: Features & Benefits 1.- Instant drying: higher production speeds 2.- Ink Brightness: gloss finish 3.- Perfect dot gain control thanks to LED pinning and UV curing 4.- Media independent: one ICC profile for different substrates % solids formulation No VOC s Máximum productivity (pay as you print). Jetted ink is deposited on the media. 6.- Best Open time: inks don t dry into printhead.

18 7.- Better separation in recycling processes thanks to hydrophobic behaviour of uv ink (corrugated board) 8.- Eliminate drying costs: No High electrical consumption Saving floor space in production plant 9.- LM Formulation: Low Odor European Regulations: Swiss Ordinance, EUPIA, Nestlé Guidance Note on Packaging Inks and others

20 Kao Chimigraf certifies that: 1.- All photoinitiators used in the CRB FDP UV inks listed on Swiss Ordinance SR Only raw materials not classified as toxic or highly toxic, mutagenic nor cancerous are used in CRB FDP UV inks according to the EuPiA Exclusion List for printing inks 3.- CRB FDP UV inks Benzophenone and ITX Free

21 4.- In appliance with the Directive 2004/12/CE regarding the cans and their residues, the contents of lead, cadmium, mercury, and hexavalent chrome is lower than 100 ppm, according to the pigments suppliers certification 5.- CRB FDP UV inks fulfill Nestlé Guidance Note on Packaging Inks
