Visit markandy.com/godigital e issue for brand owners is relatively straightforward. ey need to ensure that a simple risk assessment is completed at the initial stage of package concept design. If a migration risk is anticipated, then the package either needs to be tested to prove its migration performance and appropriate steps taken to reduce the risk, or low migration inks and coatings should be used to avoid any worries. If the testing route is chosen and it is proven that appropriate barrier performance is provided by the substrate, then the designer has a choice of using standard inks and coatings or "intermediate" mi- gration solutions. If unacceptable migration is present, then either a functional or absolute barrier can be added. Package Design Printing inks, coatings and adhesives, unless speci cally designed for that purpose, should not under normal circumstances come into direct contact with packaged foods. If it is to be t for purpose, designing packaging that is suitable for the food requires speci c information to be known. As required by good manufacturing practice, the chances of success are greatly improved if all the stakeholders in the production of the packaging are connected. at is not always straightfor ward, as some of the steps between the brand owner specifying the packaging and the consumer receiving the packaged goods may not be directly connected. e nature of the foodstu dictates how it must be packaged and once that is determined, the choice of substrate, inks and coatings can be assessed. However, every package is di erent, so the outcomes may di er according to the perceived risk of transfer of material from the packaging to the food and the barrier properties of the packaging materials used. End use properties may also in uence the choice. For example, if food is hot lled or heated in the packaging, it might lead to additional risks of migration. " The use of good packaging design and good manufacturing practices is critical to reducing the risk of unwanted migration of components." 42 FLEXO | JULY 2014
