  3. Agenda • The 4 elements for safefood packaging • Migration : Examples - Mechanisms • Regulations • Riskassessment - Migration testing • UV Low Migration systems • Siegwerk solutions : SICURA NUTRI systems 3

  4. Your and our continuous challenge is to produce safe and compliant products Example Press Articles High risk regarding food contamination & compliance 4

  5. Siegwerk offers superior product safety with inks, processes, guidance & support Four Elements to Safe Production • Safe products • Systematic processes • Product safety guidance • Proactive safety work 5

  6. Safe products – Siegwerk ensures low migration for whatever applications Influencing parameters Migration Mechanisms • Packaging structure • Printing & Converting process • Ink/ varnishes composition Associated risks to be evaluated in each case • Volume/surface ratio • Packaged good • Storage conditions • Set-off • Diffusion Substrate Packaging structure Ink Ink Migration via diffusioninto packaged good Set-off migration Benefits • SB, WB, UV or vegetable oil-based inks with best low migration standards • Information on all relevant migrants and support for risk evaluation • Safe inks reflecting the printing, conversion and end-use of whatever packaging • ! 6

  7. Concrete examples: Food packaging In-Mould Labels & Self-adhesive Labels on Cups Shrink Sleeves PP, PE or PS & Shrink Sleeves PET PS&R recommendations • Depending on storage time and thickness of bottles there is a high risk of direct migration • Possible set-off due to storage in stack. Low but existing migration risk depending on cup thickness Low migration inks and varnishes Low migration inks and varnishes 7

  8. Systematic processes – Our material introduction process excludes unwanted substances Raw Material Introduction Process New raw material Labtests Global HSEapproval Businessapproval Sample request • Checklist for Approval • Exclusion criteria (e.g., carcinogenics, mutagenics, reprotoxics, toxics) • Defined purity standards and full understanding on existing impurities • Compliance with chemical registration • Full understanding of chemical composition for food packaging Benefits • Compliant inks via highest standards in material testing and selection • Reduced claim risk since raw materials checked for impurities • Reliability based on profound analytical know-how also for critical compounds 10

  9. Product safety guidance – We share all information on critical ingredients Siegwerk Information on Relevant Migrants • Detailed information onpotential migrants • Available for all Siegwerkproducts • Statement of composition (SoC) Benefits • Full transparency on potential migrants to produce compliant food packaging • Excellent basis to perform worst-case calculations • Supporting information to prepare declaration of conformity 11

  12. The Migration Risk Labels – Sleeves 2009: What happened, when Benzophenone from Sleeves migrated... ... The HDPE bottle was not a barrier

  13. The Migration Risk - Primary with barrer but with set-off risk 2006: What happened, when ITX migrated.... PE Ink Board Alu PE PE Food Ink Board Alu PE

  14. Migration – thresholds for migrating substances are extremely low and often difficult to measure • Visual overview on migrationlimits – exampledilutionofsugar *as in various ww legislation • Specific migration limits for evaluated* substances: some ppmdown to ppb • Sugar cube (2.5 g) dissolved in • Threshold non-eva- luated substances/ no concern 10/50 ppb 2.5 literbottle 2.5 million ltank ship • 0.25 litercup 2,500 litertruck • 10 gram per kilogram (1%) • 1 gram per kilogram (1‰) • 1 milligram per kilogram (1ppm) • 1 microgram per kilogram (1ppb) • Examples for values • Alcohol in drinks • Alcohol in blood • Nitrate in water • Heavy metal in water

  16. Ensuring compliance – a complex challenge Regional regulations: European food safety regulations overview • Basic principles (Article 3): • No risky migration • No change in food composition • No deterioration of food • EU-Framework Regulation • (EU) No 1935/2004 • GMP • (EU) No 2023/2006 • Regenerated Cellulose Film • 2007/42/EC • Ceramics • 84/500/EEC • Plastic Materials • (EU) No 10/2011 • Elastomers and Rubbers • Active and Intel-ligent Materials EC/450/2009 • Positive lists • Migration limits: • a) SML-Value (Specific Migration Limit) in ppm (mg/kg) = based on 1 kg Foodstuff/simulant • b) Overall Migration limit of 10 mg/dm² resp. 60 mg/kg foodstuff/simulant • c) Calculation basis:1 kg/6 dm² resp. “as is” Food:Surface ratio • Union Guidelines on Reg. (EU) No 10/2011 on plastic materials and articles intended to come into contact with food • Union Guidance on Reg. (EU) No 10/2011 … as regards information in the supply chain

  17. What are the permissible migration thresholds? … they depend on documentation of toxicological data, and of subsequent toxicological expertise by the European Food Safety Authority EFSA Threshold (ppb) Evaluatedsubstances Specific Migration Limit (SML) 90 days Feeding Study --> X ppb Most UV standard PIs have to meet 10 ppb 50 in vitro Genotoxicity tests Non evaluatedsubstances X = depends on NOAEL (No Observed Adverse Effect Level) 10 tox data not existing 17

  18. Ensuring compliance – a complex challenge Complex value chain – responsibilities have to be shared Siegwerk proactively as-sumes responsibility by understanding the needs of each partner in the chain 1. Packaging specifications 6. Final validation Food industry 2. Packaging conception 5. Process validation • Converter Ink manu-facturer 4. Advice onhow to use ink 3. Ink develop-ment & supply Food Safety

  20. Sleeves on PEHD bottle PES cups In Mould Labels • Risk assessment – Migration testing Exposure Simulation with a liquid simulant 1-side exposure in stainless steel cells Immersion Various packaging directly filled with simulant Direct injection of simulant LC/MS State-of-the-art quantification (specific identification, sensitivity) Official or ‘in-house’ methods
