Part 1 Abstract Conventional printing inks, adhesives and polymer-based packaging materials have several harmful effects on ecological aspects as well as human well-being. Expressions of concern about impurities in food contact materials have increased over the last few years. Chemical compounds that are incorporated within polymeric materials to improve functionality, may interact with food components during processing or storage and migrate into the food. Food contact materials (FCM) may contain intentionally added substance (IAS) and non-intentionally added substance (NIAS) which comes from reaction by-products, breakdown or degradation products; impurities from raw materials used their production, chemical reaction between packaging materials and foodstuff, side products or neoformed compounds and contaminants picked up during the production and recycling process. Chemical migration of intentionally added substance (IAS), non-intentionally added substance (NIAS), and not l
