Frimpeks – Discussing the science behind low migration at drupa 2016

GERMANY • Frimpeks develops inks, varnishes and coatings. A relative newcomer in the low migration arena this specialist product category will be a major topic of discussion at the forthcoming drupa international trade fair. Frimpeks technical staff will be on hand to discuss the science behind this important shift in the ink and packaging industries (Hall 3 Stand B35).

The term “low migration packaging” is used to describe materials used in the packaging industry whose chemicals will not migrate, or move, from the packaging into the product. In the interest of food, pharmaceutical, beverage and healthcare sectors particularly. Materials include printing inks, coatings and adhesives which must not have any migratory chemicals which would affect the odour, flavour, appearance, taste, or the safety of the product contained within the packaging.

When printing a job that requires low-migration properties, there’s far more to consider than just loading up the press with a low-migration ink. In general, the term low migration ink refers to ink formulated without use of raw materials that have been identified as being able to pass through a substrate. Given there are so many different combinations of inks, print processes, and applications. Therefore printers are advised to work closely with their ink supplier to match up the substrate, process and application.

Industry commentators interpret the concept of low migration in different ways. One view is it refers to the transfer of various components from the finished package into the food product. Low migration inks really refer to products that have been developed by ink suppliers to help the printer achieve desired results in accordance with current regulations. Others focus purely on producing inks that are formulated to limit migration to the minimum parts-per-billion levels through their chemical composition.

Frimpeks prefer to look at the complete supply chain on a product by product basis. They spend time understanding the materials, production process and storage of the products right through to end use. They consider barrier properties, penetration through packaging layers, before and after filling. Set-off migration, curing variations, gas migration, condensation, heated packaging and work with our customers on their equipment cleaning processes.
