As companies everywhere strive to meet the industry standard for food safety and packaging requirements in a very complex regulatory environment, label printers are tasked with providing labels that follow ink migration limits. After all, ingredients in some inks are known harmful substances.

Migration describes the chemical exchange that can happen through to food and beverage products and the functionality of the substrate/barrier that creates that package. But it’s not that simple. Migration can be divided into four categories: Direct Migration, Through Migration, Set-Off Migration, and Vapor Phase Migration. All these individual forms can have an effect on the safety and the regulatory compliance of the product.

Thankfully, low migration inks offer a promising solution. Using selected components, these clever inks are specially formulated to ensure that migration from the ink film is within acceptable limits, which helps to reduce the risk of food contamination from ink migration and make sure that your packaging is safe. Therefore, these advanced inks are vital in ensuring consumer safety in food contact, cosmetics, nutraceutical packaging and many more applications. 

ACTEGA has developed its SafeShield range of low migration inks for use in the printing and production of food packaging, making for safer markets for consumers around the world. This product range combats all these migration types mentioned above except for direct migration.

That said, making the decision to go with low migration inks is only half the solution. To ensure your low migration ink meets all relevant regulations and standards while also achieving optimal results for the end-use needs, several steps must be taken – everything from verifying regulatory requirements to crafting an ideal printing environment. Sound daunting? Not to worry. Here’s what you need to know about navigating this process with ease and finesse.

Regulatory requirements for low migration inks

Firstly, the ink itself should meet all relevant regional and global regulations and standards for the end use of the product. Therefore, converters should be mindful of several regulations, including Swiss Ordinance Annex 6 A & B listed raw materials, Nestle 2018 Exclusion List Compliance, EUPIA Exclusion List SVHC (Substances of Very High Concern), CONEG / TPCH TSCA / REACH, and FDA Migration Models. Fortunately, tested both internally and externally by the top industry laboratories, ACTExact SafeShield UV LED inks provide complete compliance with all regulatory requirements.

Crafting a compliant printing process with low migration inks

Step 1: Ensuring a compliant printing environment with low migration inks is essential. To begin, the entire press should be wiped down with a citrus-based cleaner followed by Isopropyl Alcohol (IPA) prior to each run if you don’t have a dedicated press for running low migration inks and coatings only. This includes all press parts from the idler and roller wheels to other specific components such as impression cylinders, ink pans, metering rolls, anilox, and doctor blade assemblies.  Proper cleaning will guarantee that any residual contaminants from a non-low migration product are removed before introducing low migration inks into the press.

Step 2: If you’re looking to incorporate low migration inks into your printing process, one of the factors that might cross your mind is if there are any specific setup requirements. The answer is no, as the setup requirements for low migration inks remain consistent with those of non-low migration inks.

Step 3: When printing labels and packaging that require low migration/indirect contact inks, it is critical only to use low migration inks regardless of whether the product needs to adhere to these regulations or not. But fear not, you can always switch to different inks if the job doesn’t necessitate low migration products. Impressively, ACTEGA SafeShield inks offer comparable quality to non-low-migration inks and are a perfect option for this kind of project.

By following these guidelines and utilizing of ACTEGA SafeShield low migration inks, you can create a safe and compliant printing environment while simultaneously reducing the risk of contamination from ink migration onto food and other products. By working with the right solutions and paying careful attention to preparation and application processes, converters will feel confident that their products will exceed expectations for safety, reliability, and quality while remaining compliant with current regulations and beyond.

With ACTExact SafeShield UV LED inks, which happen to be the most extensively certified ink product line from ACTEGA to date, get ready for a worry-free future.
