Low migration coatings

One of the main tasks of packaging is to protect the contents against environmental impacts and contamination. Simultaneously, the filled goods must be protected against influences from the packaging itself. A migration – which means a transition of material from the packaging into the food – is to be absolutely avoided.

Migration can have two causes. As well as the direct transition of materials from the packaging into the filled goods, migration can result from a set-off effect. In this case, component parts of the printed and coated front side transfer to the blank rear side of the packaging, and, under certain circumstances, migrate from there into the filled goods.

TerraWet waterbased coatings are classified as low migration due to their advanced formulation. A wide spectrum of more than 50 waterbased coatings for different operational purposes has been certified and authorized by accredited testing laboratories for direct and/or indirect contact with foodstuffs.

The global migration of selected TerraWet waterbased coatings in this case has a value under a tenth of the upper limit of 10 mg/dm2 and is thus vanishingly small. The specific migration with reference to relevant components falls significantly below the existing limit values.
