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:
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
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
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.
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
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)
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)
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)
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
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
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 5.- 100 % solids formulation 5.1.- No VOC s 5.2.- Máximum productivity (pay as you print). Jetted ink is deposited on the media. 6.- Best Open time: inks don t dry into printhead.
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: 9.1.- Low Odor 9.2.- European Regulations: Swiss Ordinance, EUPIA, Nestlé Guidance Note on Packaging Inks and others
