Résumé : |
In June PPCJ, The author examined the potential markets for UV inks, and this month we explore how to formulate inks to meet the needs of new markets.
The formulation of the ink relies heavily upon the end use requirement. A growth area is in the food packaging industry where solvent based inks are frowned upon due to the VOC's being present. There are several classes of ink grades from direct contact with the food, say printing onto eggs, all the way through to exterior packaging.
Direct contact with the food obviously has the most stringent parameters to fulfill in terms of safety. Food packaging that will not come into direct contact with the food item has less stringent rules and much of the testing is done in house. Often, for historical reasons, an ink will be used with no testing, simply relying on the fact that it has 'always been used' and 'everybody else uses it'.
Very little is understood about the possible migration of materials through food packaging, especially in the areas of uncured monomers. Several barrier layers are often employed to minimise this migration but long-term effects are only estimated, as information is often gathered through simulated accelerated age testing. Despite these issues UV curing inks are growing in usage because of their durability and gloss. |
