SICURA Nutriflex 10 – a BPA-free ink series with excellent print quality
Q: What is BPA?
A: BPA stands for bisphenol A and is a chemical that has been used in the industry to harden plastics since the ‘60s. It could for example be found in polycarbonate plastics, used in containers storing food and beverages for a long time, and in epoxy resins, often used as inner coating of metal packaging like food cans.
Q: What are the concerns with BPA?
A: Some studies over the time have shown that BPA can migrate into food from containers that are made out of it. It’s still unknown which concrete effects BPA can have in people. Health agencies over the world like the European Food Safety Authority (EFSA) or the Food and Drug Administration (FDA) in the US continuously observe the results of further research on human health risks posed by exposure to BPA.
Q: What does this mean for the packaging industry?
A: Creating packaging without BPA has already became increasingly important for manufacturers over the years. In general you can say, that today brand owners and consumers expect safe food packaging which does under no circumstances contaminate the packed food or impair their health. Any migration risk of substances from the outside into the inside of the packaging needs to be limited. Product safety is the most important and challenging aspect in packaging. France was for example the first European country that adopted a law which generally prohibits the use of packaging materials in the food industry, if these materials are printed with BPA-containing inks or varnishes.
Q: How is Siegwerk handling this topic?
A: Siegwerk is a global leader in providing product safety. We have a team exclusively dedicated to safety in regards to both regulatory compliance and brand owner requirements to ensure that our products are safe for the end-use applications. The company’s packaging inks and varnishes are formulated and manufactured in accordance with Good Manufacturing Practice, taking into consideration many individual and varying parameters relating to substrate, application and end use. Siegwerk doesn’t only exclude toxic substances based on regulatory exclusion criteria but moreover design all food packaging inks to minimize the potential for the transfer (migration) of ink components of concern into food, whilst meeting the high end-use requirements. The company has implemented a comprehensive raw material introduction process striving to achieve complete knowledge of the chemical composition of all raw materials intended for food packaging inks, down to traces in ppm range. When manufacturing our products, Siegwerk does not add any BPA as intentionally added ingredient to its formulations. Besides, we have been working proactively to replace BPA based raw materials in printing inks for food packaging.
