The Biggest Hidden Risk: What is “Migration”?
Migration is the unwanted chemical transfer from label components (ink, varnish, adhesive, etc.) into food. There are two scenarios:
- Direct contact: For example, a label on a piece of fruit.
- Indirect contact: The most common risk; ink particles seeping through packaging into food. This risk increases with fatty/acidic foods and long shelf life.
Solution: Low-Migration Materials
Low-migration inks/varnishes
Special formulations and proper curing (UV, etc.) complete the polymer network and minimize free monomers, significantly reducing molecules that could migrate into food.
Food-grade adhesives
Formulations that do not react with food and contain no harmful substances; they must be selected for both direct and indirect contact scenarios.
Legal Framework: Turkey and EU
Compliance is mandatory. In Turkey: Turkish Food Codex Regulation on Materials and Articles in Contact with Food, and in the EU: (EC) No 1935/2004. Supply chain actors are expected to document compliance with a Declaration of Compliance (DoC).
Food Safety Checklist for Brands
- Supplier verification: Is the use of low-migration inks/varnishes and food grade adhesives documented?
- Application profile: Is the product fatty/liquid/acidic/dry? This determines material choice.
- Packaging barrier: Thickness and structure of glass/carton/film affect label requirements.
- Cost ≠ risk: The small price difference for a food-grade label is insurance against recalls and reputational loss.
Conclusion: Trust is the Most Valuable Ingredient
Choosing a food-contact label is a critical link in your brand’s trust chain. At Kodmark, we protect brands and consumers with low-migration inks/varnishes, food-grade adhesives, and compliant production.
